> the tracking includes all sites and pages

But it doesn't! They are proposing, in the stable version, to include only pages that opt in by calling the FLoC API.

For the origin trial in particular, to avoid a chicken-and-egg issue, they are also including pages that have ads. Since ads today make extensive use of third-party cookies for cross-site tracking, This is still not anything like "all sites and pages".

(Still speaking only for myself)
