I mean, the obvious solution is to use a strong copyleft license like AGPL and sell private licenses for closed-source projects.

if I have headphones or speakers or a mouse that aren’t plug and play on Linux which is what I’m used to on windows, I think it’s fair to say that my experience with Linux is less easy than with windows.

If that were the case, i would agree, but I dispute this claim.
Can you tell me specific models of headphones, speakers or mice that are not plug and play in any modern widely used distro?
