@Alfred, Thank you very much for making that point crystal clear. They've also made it very clear that they're not interested in making a version for Linux and the only thing that is likely change their mind is a very significant increase in Linux market share (currently at 3.6%). In the meantime, there's software such as Gravit, VivaDesigner, Pixeluvo (a Photoshop Elements equivalent), Fotoxx plus there's Windows software that works well with Wine including, but not limited to, Photoline (a full Photoshop equivalent), Photoscape and versions of Photoshop and Paintshop Pro.

Nevertheless, Mac users now being able to play Apple Arcade games natively will not make up for the loss of existing, and non-porting of future, AAA games. Similarly, the loss of CAD, scientific, engineering, architectural, 3D compositing, etc softwares will ultimately only benefit Linux and Windows market shares and when Linux achieves that critical market share (thanks in part to Apple's own decision making), that's when porting over the range of Affinity products to Linux will become viable.

^ Now that is an eminently sensible and realistic comment and thank you for that.

Here's the thing though - Serif is two orders of magnitude smaller than the giant Adobe corporation and when smaller companies expand and overextend too quickly then it can often have an unhappy ending. Right now, Serif has produced three professional quality software packages that rival what Adobe and others put out. Personally, I think it's better that they keep on updating and improving these great products at this time rather than expand into new software areas, e.g. DAM, RAW editor, video editor and so on where there is already existing very strong competition from both paid-for and free software products.

Linux has been growing recently (3.6% market share now) and I assume that this is due to factors like more people trying/using Linux at home during the Covid-19 lockdowns across the planet. I expect that trend will increase not least because any Intel MacBook bought now will become unsupported after a couple of years and I suspect that will push quite a few current Apple customers over to Windows and Linux. Even Autodesk seems to be tiring of Apple management's antics and they've now discontinued Mac support for Autodesk's Alias and VRED software packages (and I suspect that more of this will happen).

@Patrick, I'm not going to mention any particular names, but what some other companies do is try to make sure that their Windows software also works well with Wine so that Linux users can also benefit from that software. Is it potentially possible for Serif to look into that compromise option at some time in the future?

While I understand the calls for Serif to produce a RAW editor like Lightroom, that market is already crowded with paid-for and free alternatives such as ON1 Photo RAW and Darktable. I'm not sure that it's worth their while entering that saturated market while they have other very good existing products that need to be kept up to date.

I understand the calls for a DAM but Serif isn't (yet) a multi-billion dollar company and I think it's better that Serif concentrates on a few very good software products as at present rather than spread themselves too thinly to produce many mediocre products. There's no shortage of good software already out there such as Exposure X5 etc.

It might also be the case that quite a few people are using their home Linux computers to do their normal work on as opposed to their work-based Windows PCs. In any event, for Serif to consider porting over their software to Linux, the Linux desktop market share would have to be broadly comparable to the macOS market share. Until such time as that happens, I fully expect Serif staff to keep on confirming that their rather good software will not be available on the Linux platform. There has also been an interesting development today in the form the news that Apple are now expected to announce their plans for ARM-based Macs at their WWDC and that the transition away from Intel to ARM will begin in 2021. I am already seeing a lot of concern from professional and creative users of Macs about this move, e.g. what happens to their very useful software and how will they be able to use Windows beside macOS on these new ARM MacBooks. If this transition is handled badly by Apple management then that could very well result in more converts to both Windows and Linux, i.e. Linux desktop market share going up for an additional reason (it might also mean a lot of hackintosh users needing a new home to go to).

^ That is an excellent and helpful post and PageStream is also available for Linux although it does have an old school interface. That said, the full professional version is cheaper than VivaDesigner.

I fully agree with you and the Serif staff have been quite adamant that there is not going to be a Linux version of their softwares because it's just not economical to do that. Despite that, the whining goes on and it will achieve absolutely nothing. These days, I mostly use native Linux Nomacs and Pixeluvo (= Photoshop Elements equivalent) and there are now quite a few other image/photo editors available for Linux both in and outside of the formal software centres. Some of that software is actually Windows software that's been bundled with Wine to make a Snap (Photoscape, Irfanview, etc). If anyone wants even more choice than that, there are versions of Photoshop and Paintshop Pro that work well with Wine (see Wine HQ at winehq{dot}org) and the developers of PhotoLine (like Fotoxx, that software ought to be more widely known about) go out of their way to ensure that their software works well Wine so that Linux users are not unduly disadvantaged. Then there are the numerous online image editors to use as well. Finally, and just for the record, I am a full time Linux user:

What I'd suggest doing is looking online for Youtube videos and and forum requests and answers - Good luck!

In which case, I'd suggest heading over to the free and open source image editor and image organiser that is Fotoxx (infos available at kornelix{dot}net). That Linux-only software can do photo stitching and panorama creation and Fotoxx ought to be more widely known about.

I'm afraid that our developer friends at Serif have made it crystal clear that they're not going to develop versions of their rather good software (even J Cristina is now recommending their products which is a good endorsement) because the Linux user base is currently so relatively low and no amount of attempted fundraising would change that fundamental fact. Therefore, the options that a Linux user has include using native Linux alternatives (the Deepin software center has a comprehensive list of native Linux options as does Alternativeto), dual booting with a supported operating system, using a supported operating system in a virtual machine or looking through Wine HQ to see what alternatives to these products work well with Wine on Linux, e.g. PhotoLine, some versions of Paintshop Pro, Photoshop, Photoshop Elements and so on. My tip there is to only try software with a Silver or above rating for best results. Finally, Photopea is a good online alternative (I have tried that one) and someone's made an unofficial electron app out of it too (the landsman one, not tried it yet).

Thank you for posting that video and in case it is of interest, in January's edition of Astronomy Now magazine, the experienced astrophotographer Nik Szymanek described Affinity Photo as an excellent alternative to Adobe's Photoshop (that was part 1 of a series on the use of Affinity Photo, the latest being part 3 in April's issue of that magazine).
