I play a number of commercial games on Linux. The best behaved ones are the native ones (Factorio, Stardew, Celeste), though the Proton/Wine-based ones (Noita, Enter the Gungeon) usually do alright as well.

Netflix's problem is Netflix's problem. There is no technical reason why 1080p (and probably 4k) can't work on Linux, today. That's just plain ole head-up-DRM-ass, and Linux can't fix stupid.

That's another goalpost. That's because DRM doesn't go well with Open source.

Netflix works, just not 4k. Blender and Davinci Resolve say there's commercial software, just not actual Photoshop.

Correct, you have just successfully identified the reason why Windows exists. Well done!
