There's at least three good reasons: * Keeping the protocol private is a competitive advantage * Licensing a protocol and managing those licensees is not free * A shared protocol dramatically decreases Apple's ability to innovate on top of that protocol I would argue that it'd be worth while to ignore these issues if Apple was hampering competition in the messaging space, but I just don't see it. I can easily use any messaging app I want on my phone, the only thing stopping me is that iMessage is good enough.
