Chills

I gave a factual technical answer.   The answer was helpful in that it gave the reasons and timescales for the TPM hardware that the commercial/corporate IT departments wanted. Hence, the ISO/ IEC standard in 2009.   In my experience, having worked on both  ISO and ICE standards, the IEC standards tend to be industry lead and faster than ISO standards. This is why motherboards started to get TPM support over 15 years ago, it was not just Microsoft doing it.
Now most people don't change PC's every 2 years but most get changed after a decade because the software they use evolves. (it's far worse on Apple for having to upgrade hardware) So by the time Win11 came out all new PC's for the previous ten years would have had TPM And be Win11 compliant.    

So yes, my post was intended to be helpful to explain the timescales on the TPM and that it was industry lead. MS put it in because it was wanted by the majority of users (the cooperates) 
Your reply was emotive and lots of guessing and incorrect assumptions.
BTW my PC was spec'ed for video editing using BMD Resolve Studio. (there is a Linux version of Resolve)  It was also bough by my company to last for a decade (or more) hence the 128GB.  The minimum RAM for Resolve Studio is 32GB with 64GB recommended. So it made financial sense on the original build to go to the 128GB  which was the max for the motherboard.  The additional cost was negligible.   The NVIDIA 3080TI was "reasonable " but nowhere near the top spec for a video edit PC. the same with the CPU.   

So whilst my PC is overkill for Affinity and below par for serious gaming, it is the sweet spot for video editing with Resolve. Well, it was when it was built 3 years ago. now, it would have the next gen GPU and CPU's.  This is purely technical and economics because I am an Engineer and think like that.   
EDIT:- Just been told that my 1080 res screens will need upgrading for the latest version of Resolve V20, as it needs 1440 Res screens as a minimum.  Also Resolve is designed to worth with three screens.   So despite your obvious complexes it has nothing to do with "measuring contest of reproductive organs,"  but the requirements of the software my PC was spec'ed for.   The actual spec was worked out with a custom PC builder that does PC's for video editing, gamers etc  and the cameras have by  far the more powerful PCs

Yes, a fresh start would be ideal. 
 
In the meantime a Linux release would be more than welcomed by those of us who would like to break free of Mac and Windows.

To be fair: NO ONE understood the significance at the time.  It was only looking back with hindsight a few years alter that you could see how all the pieces moved. 
Fortunately, I can still remember the discussion over dinner as the same person was explaining why there is no such language as C/C++ 

You're still incorrect. UNIX is a trademarked lowest-common-denominator standard, not some magical inherently secure operating system which Linux is not.

Aerospace and automotive embedded use-cases and related government agency approval peculiarities are not relevant for Desktop Linux discussion anyway.

Lot software Linux users, or at least some that I read seem to think getting software developers to do things SO Linux will grow as in what I quoted. Yes Linux needs to grow before serious software developers will start looking at it, but it is not the job of the software developers to grow the various flavors of Linux that are out there. 

I would love the entire Affinity suite on Linux, it would become the most (only?) powerful photo, vector graphics, and desktop publishing packages available on Linux.
However, in defence of Serif and Canva: one does not simply package software for 'Linux'.
Linus Torvalds on the subject at DebConf '14 (~10 years ago, so may not be as true now but explains some of the difficulties):
Linus explains he's not talking about X, Y, or Z packages improving over time... (some paraphrasing to make the below quote a bit more readable, some errors may be present)
I guess the somewhat uncomfortable truth about getting any of the Affinity suite on Linux right now is that it won't happen without a somewhat stable architecture/SDK, more-so than now according to Linus, admittedly 10 years ago now.
Compiling from scratch is out of the question because one presumes that Serif/Canva won't release the source code to the Affinity suite, nor should they be forced to.
Perhaps the tact Serif/Canva need to take is by contributing code/developer time/funding (as Serif/Canva do have commercial interests here) to existing systems, such as WINE or Proton, that can allow Windows binaries of the Affinity suite to run on Linux instead?
Serif certainly know the Affinity suite inside-out in terms of what ABI/API functionality is required to make each suite function, so investing time, money, or effort into WINE or Proton (preferably both) seems like a reasonable solution over re-packaging the entire suite just for one Linux distribution let alone several, should the commercial viability and business case exist.

 

But you certainly can't expect Serif and similar private companies to solve this problem, meaning that they invest huge amounts of money into product development and then "hope" that this money will be returned to them.

Yes, but that is only one of many OS's out there that fit the bill.  Linux doesn't but many certified UNIX and other POSIX OS do. 
For any Linux fans, I suggest you read the Tanenbaum-Torvold debate. 
I would think that as the world, at lest the hardware side of computing, has moved on 40+ years it would be worth a complete new ground up design (by experts)   someting with a similar message passing architecture like this  https://www.sciopta.com/safetykrn/ Though I would not suggest that OS but something new starting with today's CPUs for a General purpose computer. 

 
 

I do not. To be a certified UNIX, the system has to comply to certain POSIX APIs. That's it. The historical heritage and direct descent from the Bell Labs code base is not required. Linux distributions can be UNIX. It's a matter of money for certification.

It’s not the MacOS that I have a problem with really, it just that it out grows the computer. The lack of ability to upgrade or fix the hardware, Macs are built to last at least physically but the shelf life is decreasing constantly. 5-7 years and it won’t run the latest OS, and consequently up to date software; despite the fact that physically the machine is fine and only needs a couple of new components that Apple make impossible to upgrade. 
To summarise Apple make life very expensive, it even has a knock on effect to peripherals such as Wacom compatibility, software becomes obsolete add ons, docs cables the list is endless. 
I’m ranting now, sorry I’m just tired of the lack of thought and greed.
I left Adobe and moved to Affinity because of similar reasons. I currently feel the same way about Apple as I did about Adobe.

That is highly unlikely to happen and so CodeWeavers ought to make the first move. Why not head over CodeWeavers' forums and make that constructive suggestion of yours?

This is not going to happen and Serif Europe have made that crystal clear. It would be far better for everyone to head over to CodeWeavers' website and ask them to make the Affinity range a priority for their CrossOver product.
In the meantime, using the Affinity softwares on Linux via a Windows VM works well or there is the alternative Bottles/Wine route to try out. 

Windows is responsible for creating thumbnail previews and requires so-called preview handlers. For .heif/.heic, there is a free extension for this in the Windows Store.

More likely is Canva's media people want to see everything first and/or Canva are still evolving the road map?
 
NO, and I would not like to have updates every two weeks. That is a bad sign for software.

The problem is that for the last quarter century Linux oscillates between  1% and 4.5% of the desktop market. (I don't think it ever quite hits 5%)  
In the last 30 years, but effectively (since Win 3.0) the same 25-year time period, Windows has gone from zero to about 80% of the desktop market until OSX and Apple took off. Apple  "only" hold 15% but that is overwhelmingly in the professional media/arts market, a target for Affinity, BMD etc.  Also the Apple users do spend money.  

Apple and Windows have a tightly controlled road-map that, under NDA's companies could have access to years in advance. There is nothing comparable for Linux.

Because you never get stable software.  Adding in lots of small things requires a lot of regression testing for unexpected side effects. You never end up fully testing the system. Also, you have problems adding larger changes that take weeks or months to do if you are releasing every couple of weeks. It is an extremely inefficient way of working, and you rarely ever get bug free software.

Adobe are raising their subscription price in order to cover the new AI features they seem to want more than any of their customers do.
Windows Recall continues to be a security nightmare and the worst idea in the history of computing.
Windows 10 is rapidly approaching the cliff, and many people with perfectly good PCs cannot upgrade to 11 without buying new hardware.
The next couple of years will see a lot of people looking for an alternative. This would be the perfect time to capture that market with a product people actually want.

Not at all. IF they want to expand in to the professional markets and eat adobe's lunch, then they will increase staff and investment.
As for proprietary code. That works both ways.

It is still a single point failure.
So no planning, no future road map. All this takes time and effort,  No sanity checks.
How long does a full regression test take?  

I have no idea but I do know it can't be a full-time job for him. As a one-man company he is Developer, test department, project manager, Accountant, Company Secretary, MD, Marketing department, Sales department and Webmaster.  Serif have multiple people doing most of those roles.     So whilst it is impressive what one person has done, it is also a single point of failure.
If a Serif developer gets hit by the proverbial bus, there are others that will carry on. (and the other roles are not affected)  If NumericPath Oy has *ANY* problem, the whole thing stops.   This is why there are several thousand obsolete and unsupported Linux Distros. All developed by one person or a couple of friends and when they find other things to do.... Actually it was the same with most Public Domain software from the 1980s  as the developer found other things became more important in their life the software stopped.
Actually I personally know of half a dozen companies of 1-4 people that stopped because the primary driver retired, found a better paid job, had an illness or a family problem.
NOTE I am not knocking NumericPath Oy, or his software, just stating the way of the world and the evidence I have seen for the last 40 years. Unless NumericPath Oy, becomes a multi person company or is bought out, I would not depend on his software.
The same is happening with Serif at a different level in that they now have a lot more resources and back up for development.   Though remember that Canva bought Serif because, primarily, it fits with Canva's plans Serif's plans are secondary no matter how much good will there was at the purchase.
