I mean, exactly how invasive are default operating systems? (Like Windows, Mac, Chrome OS, Android, iOS) Do they log your keystrokes, log passwords, capture screen, upload your photos, videos, or audio? (Assuming you aren’t a target of government) Is it even possible for the average person who doesn’t feel comfortable messing with installing operating systems to have any privacy?
Believe me, I’ve tried my bluetooth headphones and while they worked for a while, they eventually stopped working, and I had to dig into the command line, and spend hours on searching to try to and get them working again.
The only bluetooth issue I had was with an xbox controller that I used both in both windows and linux (same machine). I had to completely remove it and pair it on both OSes if I used it on the other one.
Idk if this is helpful but as someone that had issues with BT in Linux, I found it was a combination of my computer AND the device both had issues. On a separate laptop and a separate set of headphones it worked perfectly from jump. This was on kubuntu.
