"There's a small corner where they're just as bad! Checkmate!"

I totally agree that should be swappable, but what is your point? Apple doesn't even allow installing stuff outside their store in most places, and had to be legally forced to do it in some because of how ridiculous that obviously is (thanks, EU!). And even there they still have some control with their notarization process. Android is wildly more open in major, meaningful ways, despite some failures.

Well that's a totally different problem from restricting which apps you are allowed to install
