Apple is writing their own death sentence here. Beeper Mini's case will definitely be used against them when their anti-monopoly case inevitably comes about: 1. Forcing a monopoly when they force-migrated their users to iMessage 2. Maintaining said monopoly by keeping third parties out Best thing they could do is put third party clients into a MFI like program and loads of red tape.
Why do you think an anti-monopoly case will ever come? Europe has dropped it, and US pretty much everyone in power (and all their families/friends) is an iphone user. They're probably completely unaware that there's a problem, and even if made aware they have positive vibes for Big Gray

It is very much possible that the current kerfuffle has some bearing on future regulation.
That said, iMessage is not really big in Europe, Whatsapp is, so it's more interesting for the EU to regulate that.
