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?
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.
