Unpacking Google’s Web Environment Integrity specification

This is especially rich coming from google's, who's 'safetynet' for android results in a significant reduction in security (contrary to its stated purpose): it locks out 3rd-party up-to-date and secure ROMs while allowing horrificly insecure manufacturer-provided ROMs to still pass, because to disable those would cause a massive user outcry. So it functions as a vendor lock-in but no meaningful increase in security for the average user, while preventing more advanced users from improving their security without needing to buy more hardware. This needs to be called out more to push back against the claim that this kind of attestation somehow has a legitimate benefit for the users.

And speaking of user-hostile, locked-down phones...

a galactic irony that Ben Wiser, the Googler who posted this proposal, has a blog where his most recent post is a rant about how he's being unfairly restricted and can't freely run the software he wants on his own device.

Not the same thing. Attestation doesn't mean you can't run software you want on your own phone, which Android allows despite having build attestation APIs.
