The author feels comfortable enough to claim by himself that the "privacy" "sandbox" is neither private or a sandbox. That is not a quote. Google isn't fooling anyone with this move.

The alleged "five major goals" behind FLoC v2 aka Topics:

1. Fighting spam and fraud: it doesn't.
2. Showing relevant ads and content: except that most people despise advertisement, and the better informed ones avoid targetted advertisement even further.
3. Measuring digital advertisement: besides Google itself, nobody cares that much about this shit. And Google only cares about it to min-max profits.
4. Strengthening cross-site privacy boundaries: I'm really sceptic on this.
5. Limiting covert tracking: while overt tracking goes rampant, right?

"Topics is a response to pushback against Google’s proposed Federated Learning of Cohorts (FLoC), which we called 'a terrible idea' because it gave Google even more control over advertising in its browser while not truly protecting user privacy," said Thorin Klosowski, EFF security and privacy activist, in a web essay.

I'm preaching to the choir given the comm, but that's why one doesn't trust Google. It forces it until it gets things going its way.

I wonder how much this means that people shouldn't touch even Chromium with a 3m pole.
