I have a website that shows up when someone searches my name on the internet and an email there. This way people are able to contact me and I don't have to use any spyware like Facebook.
But whether that works for you depends on your threat model, I guess.
On Android, when an app needs something like camera or location or whatever, you have to give it permission. Why isn't there something like this on Linux desktop? Or at least not by default when you install something through package manager.
