Those restrictions aren't on your desktop, where you do have root. Why would they be on your phone if you had root on that?

[jbombadil]

They are on your desktop. Have you tried installing any game you bought through Steam lately? They all install a custom launcher / updater / stuff that ends up in startup.

Literally 0 games I own on steam have any startup items. Custom launchers yes, but not startup items. A few games have kernel anticheat, but they all start with the game.

The exception is FaceIt for counter strike, but that’s not distributed through steam and is entirely third-party.

What? No they don't. I'm not saying that no game does this, but I play lots of games on Steam and none of the ones I play do it.
