Most of your "people who should think about staying on Windows" are not typical users, outside of AAA multiplayer specifically (currently, though it looks like EA at least is maybe changing). Yeah, it's harder to play games from sources other than Steam, Epic, GoG, but how many are? If you are, then you're also probably technically knowledgeable and you'll be fine. No one who "doesn't know shit" about computers is getting things from sources besides these.
For someone who has used only windows in the last 20 years and is used to a specific workflow for whatever they wanna do... , it will most likely be hard to switch over too - and why should they?
This is the point I made. It's easier on Linux often (OK, maybe not that niche thing, but who's doing that?). It requires relearning though. They probably dealt with a lot of shit setting the work flow up in Windows. I'm not saying they should change. However, I am saying comparing switching to Linux from Windows is not the same as comparing Linux and Windows. In a vacuum, for the average user, I'm almost certain Linux is easier at this point. Just compare the install process for most common distros to that of Windows. It's crazy how much simpler and easier it is. Is that easier than just doing nothing? Obviously not, and that's not what I claimed.
