Overall thinking, this is a shame, there is no really good software (beside Krita and Blender) that can produce print ready results.
I understand, linux users would love to have an open source alternative, and that Serif as a company need to make money, as they develop great apps, and neet it to get company running, and earn - this is perfectly fine.
I understand standpoint that *some* of Linux users whoes says that on that system souldn't be any paid software (or at least commercial in any form), in the end this is fully opened source envirioment (beside some examples like enterprise solutions etc.). Just look at problems with graphic card drivers, You need to install *proprietary * drivers alone in some distros, and on some this is just impossible to do, cause the open-source nature.
I also understand, that Serif is worried about small Linux userbase that would buy software on Linux, and that they cannot get back money and reources invested to port their software. And also that, there is so many Linux flavours, hardvare combinations etc. that would have negative influence on porting software. Just imagine situation when users buys software and it's laggy or evend to not run, on system just because there is some differencies in kernels/x-driver or something else.
But I cannot understand that *any* of big players on graphic design software companies field, cannot at least try to make Linux users life easier, trough a ports or at least improve usage by helping Wine team.
Personally I think that would give only good PR, and first company that step inside Linux world, would be for first a pioneer, and for second *winner* on that field, which could be a perminent trend, an maybe which some time earn new userbase. I know many fellow indie gamedevs, working strongly in Linux space, and having only second partition with Windows for graphic workflow, and they would love to play around only on Linux.
And now Me, for most time I'm a proffesional graphic designer (working in this industry over 15 years), but in recent time as a hobby rather than a job, I'm building mobile apps and games, mostly working on them on Linux, and this would be perfect when i wasn't forced to reboot to second os every time when i need to modify or make new assets. So - yes, I would love to see Affinity software on Linux platform.
Sorry for a long post, but this is only my thinking about this case.
