Unless there is a plan to allow attesters that are independent bodies then this is absolutely a threat to the open internet, or what's left of it.
The biggest dead canary for me is the lack of calling this out explicitly by Google or Apple. We're left to assume that Google is hand-wavingly saying "don't worry we can take care of that" when the private companies already monopolizing parts of the Internet are the absolute last people we want handling attestation.
Or what is wrong with meeting politicians what have always a very good brief in their hands telling them what words have maximum impact on the small group before them? It seems to work looking at the increasing number of spineless chameleons.
So many people genuinely don't understand what would be wrong with this scenario, and that's why I'm afraid.
