I was one of those nomadic users, every year, since 1998 with Mandrake Linux.
I have always been in love with the idea of an open source OS, but if I couldn't game and work on it, it wasn't ready. Every year, until Valve made it easy to game on Linux.
I made the switch when Proton was released and never looked back.
My point is, every time users go back to Windows, they have their own personal reasons, but those will some day not be the truth anymore.
