You can disable them, which is the same thing as far as the user is concerned. Uninstalling from a read-only partition doesn't make sense.
otherwise why allocate disk space to be read only and have apps on it people might not want? (as far as user experience is concerned)
i meant they can maintain an app store experience without the bottlneck of downloading expected apps on day 1. instead of downloading and using data an wasting time, it would enable the app. so its the same "opt-in" experience as downloading but with benefits
Not usable space.
> they often are re-enabled automatically whenever the device gets updated
This has never happened for me.
