GrapheneOS is weird. It's advertised as "privacy- and security-focused" but in reality it's a great OS for everyone, it's like a pure version of Android without being too tied to Apple or Google. You can use the Play Store if you have an account, or Aurora if you don't want one, and F-Droid is there for the weird stuff.
And what made me switch, it has fucking Android Auto to listen to the music in my car. It's a bit tied to Google but it's a huge bonus for me. And for work applications, the Google account is still available but sandboxed.
Computer were invented way before that, and I was there and don't remember seeing idiots like that in the past.
