I'm failing to see why they didn't just adopt Private Access Tokens (not that they're great either), where they could have at least:
- pretended that it wasn't all about invading peoples' privacy.
- done a good ol' fashioned "but Apple does it"
- pretended to be standards-oriented
- advertised it as something completely transparent to the end-user
Seems like that would've caused a lot less backlash while still achieving the goal of having some form of device attestation -- but I'm guessing that's not the real goal.
It doesn't fundamentally solve anything. You want to be able to identify a specific person or at least a relatively expensive device so that if you ban them they stay banned.
This is the exact method used to secure iMessage against spam: secure attestation and ‘console’ bans of devices (reversible by iirc phoning support, indicating who you purchased the used device from, and providing an ID). But Google is trying to pull a Windows 11 “TPM or die” conversion on the public Internet via Recaptcha. Welcome to the attestation wars, unwitting websites :)
