The last I’ll say on Beeper/Apple/iMessage debacle:
I think it’s within Beeper’s right to attempt at reverse engineering iMessage, but not Apple’s responsibility to be forced or even expected to host Beeper customers. It’s clear Apple doesn’t want to and I don’t blame them. If this ever went to court, Apple would obliterate Beeper—even if they switched lawyers. It’s not Beeper’s right to push the burden and expense of hosting on Apple.
