A few years ago I got 5 of my millennial friends to move from FB Messenger to Telegram and it took some peer pressure from me and essentially one hangout where we were all together, and moved in one go. Telegram is not perfect but overall it’s much better than being on FB messenger.
Regarding your bluetooth issues on your 8bitdo, I had an issue with my 8bitdo pro 2 where on linux there was a higher input delay vs Windows. I then updated the controller firmware and that fixed it. Works great on linux now.
Maybe try updating the controller’s firmware, if you haven’t yet anyway.
Regarding dual booting, I do dual boot, sometimes I like using windows, others i like using linux. It’s nice to have the flexibility. Ideally i would like to switch to linux one day, but there are still a few small issues, at least on KDE wayland.
