This post is about Google pushing RCS to other platforms. I’m pointing out why their competitor, Apple, has not done the same with RCS’s competitor, iMessage. It’s an apples-to-apples comparison, and I consider it relevant to be mindful of this particular difference when considering RCS.

Google could have implemented crypto-signed device identifier attestation as a mandatory requirement for RCS, which would have given them considerable leverage against iMessage. Why wouldn’t they? What was more important to them than stopping texting spam?
