Wine is not another platform, as you very well know Joanna.
For those who are not familiar with Wine, it is a framework to allow Windows apps to allow on other platforms without running all of Windows. Most applications run decently under Wine. The GPU acceleration of DeepPrime would be the most difficult part to port but Prime would run fine in CPU emulation. It’s quite possible to get an application up and running well in Wine with a minimum level of participation from the developer (usually it’s switching a few calls from being hardware specific to more generic).
Affinity Photo, World of Warcraft, Starcraft, .NET, The Witcher, Left4Dead, Adobe Photoshop CS6, iTunes all run very well under Wine. I see no reason why PhotoLab could not join this list.
I’m not even a Linux user but I can definitely see the advantages to DxO getting a foothold in the Linux market by supporting Wine for now. There’s something called mindshare, and the people running Linux are disproportionately influential in IT.
Have at it Holy Warriors, just don’t expect me to participate in your OS wars. Windows has been US commercial spyware since Windows 3.x (National Security was Microsoft’s trump card in the antitrust lawsuit), OS X joined the party in 2012 with OS X 10.6 and more specifically 10.6.8.
Before that Steve Jobs refused to deliberately compromise the privacy and security of Mac OS or OS X. Then he died.
