I feel like trying to persuade people to leave Windows purely from a privacy angle is being too specific or extreme for those who really don’t care/gave up. I think a great, alternative way to win people over would be to simply point out how much more efficient it is and energy-saving for their own electric bills.
Just don’t warn them about how much energy they may end up ironically expending as a result of tinkering with it and fixing issues and finding cool stuff like Burn My Windows, haha… 🤫
Been using Nvidia on Linux for a long time and it mostly works just fine. On occasion a game doesn’t work right, in which case I wait a while on that particular game until it does work.
