This is simply unacceptable. You are not making an innocent pragmatic compromise here, you are launching digital infrastructure which initially will tie everyone to Google/Apple and give alternatives a huge disadvantage for an unknown amount of time. Nobody knows when, or even if ever, support for open platforms will arrive.

You should be ashamed of being involved in this monopoly handover to American big tech.

I bet £50 that the alternative (eg GrapheneOS attestation (based on the standard AOSP attestation)) will be delayed, then delayed, then scrapped since almost everyone is using Google Plag integrity anyway.

Yes, I assume malicious intent, sorry, seen this happen enough tines recently.

Fingers crossed for the judiciary - if the implementers ignore the intention of the law, then lawyers will have to help them understand the limits of corner cutting - and block this.
