Hmm, like disallow them in the AppStore but allow sideloading apps, even an alternative app store - and then put a large banner that it is insecure blabla that the user can ignore if he/she so chooses. Or allow it only with some developer mode for which a user would have to touch something n times , like it is on Android. So those who don’t know what is it all about can stay in their walled garden, while the rest can use their goddamn 1000 dollar phone the way they want
