If I understand correctly, couldn't you just provide a static FLoC that isn't personalized? How will the sites know whether what they're receiving is actually personalized or not?

This is my question - unless this ties in with a model to rely on trusted computing, a system receiving a FLoC shouldn't be able to validate it. That means a browser plugin could simply return "0000".

Unless this ends up as some closed source DRM style blob (in which case we might as well kiss goodbye to the open web that can be accessed by standards compliant browsers), I can't see how anyone can stop this.

On the other hand, given the widespread use of ad blockers and tracking block lists, perhaps this simply isn't a design goal - just accept that 20% of techies will block it anyway and return 0 or simply not run a browser that supports it, and focus on the majority who think Chrome is synonymous with "the internet" and run it without add-ons.
