> I don't get why you would regulate such a thing. Because there's absolutely no downside to telling Apple it can't artificially make its iMessage platform restricted to Apple devices. We literally have seen leaked emails where Apple deliberately does this as an anti-consumer platform lock in play. The slippery slope hypothetical you provide is not the reality. Nobody is asking governments to regulate adding cool new…
> Because there's absolutely no downside to telling Apple it can't artificially make its iMessage platform restricted to Apple devices. I would assume one downside is a higher amount of spam. Currently you need to have an Apple device to send an iMessage. So sending spam is an expensive proposition.
If I want to spam you I buy a bunch of numbers on Plivo and start sending your number messages with SMS, the existing standard. They show up in iMessage on your phone. The only difference is they're green instead of blue.
So, how do I need an iPhone to send you spam? iMessage doesn't do anything related to spam other than let you delete and report it.
But if it did work that way, then the standard could include that messages need to be signed with a device attestation key from an approved vendor or something like that. There could be a way to have your attestation keys registered like we do for CAs today so that your attestation hardware could be used. Phone manufacturers would all implement device attestation, like Apple and Google do.
