Apple’s Messages app, why does it only support iMessage and SMS? iChat had support for AIM, Yahoo Messanger, ICQ, and XMPP. Why hasn’t Apple gone beyond the blue and green bubbles, introducing support for additional protocols with more message bubble colors?
Apple likes control. They didn’t have it with those protocols. How could they implement things like CSAM?
