I see that Affinity has a very strong resistance to launch a version for linux.
In hollywood more linux is used than windows and I believe that it can make many users who already use windows and want to change their systems go to linux.
The company is in doubt if it will recover the money or not and I think so, if it was not worth launching Linux software to Editshare and Black Magic would not launch its video editors for linux.
I see a lot of excuses for not launching your software for linux, I think you should review it, because it sounds prejudiced
