This is why I like the hybrid approach that Android has for apps, at least as of 2020.

That it has its walled garden, but it is possible to install from arbitrary sources (with sufficient warnings to users of those dangers). In iOS, you can't sideload at all.

The flow for installing apps outside of Google's approved method on Android breaks 3rd party app stores like F-Droid, such that automatic updates of apps installed via F-Droid, or updating several foreign apps at the same time, cannot work.
