I don't really want to go to Android, but as was pointed out above, at least side loading is possible. Everyone still can get Element right now, even though Google has banned it from their store. But if Apple banned it, I'd be immediately unable to get it.
You can use an open source community driven Android build like LineageOS or GraniteOS, if your phone supports it. You can even conpletely degoogle your phone this way :)
I’m seriously considering ditching my iPhones for any Nokia dumb phone. But what we really need is a mobile OS that is really free with no marketing BS, ideally BSD derived.
Paler, maybe? or Parter?
