IANAL, but I think the gdpr/antitrust case lies in the other direction,E.g not in [login on google/youtube]->[logged in in chrome] but in [logged in in chrome]

IANAL, but I think the gdpr/antitrust case lies in the other direction,E.g not in [login on google/youtube]->[logged in in chrome] but in [logged in in chrome] ->[Can't use youtube/google anonymously]. If we take all of googles privacy controls and privacy policies for the truth, they now have an additional way to track me and I can't disable this without completely missing out on any other google service. This propably also circumvents any installed cookie blockers (but only for google) which could be interpreted as not honoring the denial of tracking.
