I agree with you. I also suspect Apple's iMessage system is not nearly as secure as they claim it is. So if someone can post the full crypto protocol, others will find bugs/ backdoors* in it and you will have one more reason not to trust closed source secure communication software.
* By backdoor, I mean the protocol isn't actually end to end secure in the way Apple claims(i.e. safe from NSLs) and Apple does actually have access to messages. Not that the protocol looks secure and they picked backdoored primitives or some secrete key escrow scheme, though they may have done the latee at least in other cases[0]
