For my sins, I do dual boot Windows 10. Though with wine and proton I reckon I can get ~80-90% of games to work.
I’d love to go 100% Linux, and I do my best to only buy games that support Linux. But there are sadly some old games and multiplayer games with friends that I still can’t quite convince to work.
So you’re taking the best aspects of any fork you can find? Trust in the developers is 99% of the question.
If a piece of software passes every audit in the whole world, but is developed and maintained by the NSA, you’d be stupid to leave your data with it.
