> An unofficial third party client breaks an established network of trust I think this is key. The problem is the security of iMessage as a protocol is dependent on trust between client (implementations). Which is actually not that great from a security perspective. I don’t mean that there are necessarily vulnerabilities in the protocol (there very well may be), but that the protocol is not something that Apple is willing to depend upon to uphold their desired security guarantees.
