Maybe your hypothesis that device attestation is the answer to spam is just… wrong?
Maybe Google doesn't think you need device attestation to manage spam on a messaging platform. There are numerous examples of apps today that don’t suffer from spam and don’t use device attestation. And there are examples of spam on iMessage.
Furthermore, I can already receive messages on my iPhone from non-iMessage users so I don’t even understand how any of what you’re saying makes sense in the first place. RCS is a protocol (not a platform) that would make the experience of receiving those messages better. It does not add some new attack vector for spammers.
Have you tried using a device with an RCS messenger app and been plagued with spam more-so than on iPhone? I switch between devices all the time and have not noticed any difference.
It’s not about spam. It’s about Apple playing lazy/dirty. Hence the OP.
