@dang The title is misleading. Apple is not banning other browsers (there are over 100+ browsers on iOS). Apple is restricting iOS browsers to using the WebKit rendering engine which is an entirely different matter. Edit: Apple is also not claiming what the title suggests (source would be needed), the author of the tweet seems to just interpret it this way.
It's not misleading. Firefox, Edge and Chrome have all been banned on iOS. Instead Apple has forced them to produce separate browsers around a locked WebView that they exclusively control. Mozilla, Microsoft and Google have all spoken out against the ban in regulatory submission, and browser engineers at each vendor consider it a ban. The REAL browsers have been banned.
No they haven't! You can download each one here: [0], [1], [2]. They have been forbidden from using their own rendering engines. But they can still add all the chrome they want to the UI and do all their usual tracking like they do on the desktop.
