The thing is, the consequences seem to be very much intended. The consequences of forcing companies to be transparent about tracking, and hopefully letting the users start voting with their wallets as they get annoyed by the omnipresent "We Value Your Privacy"-popups (which is very ironic considering all the dark patterns et al that are used to have users get tracked).

If nothing else, at least now people know just how much they've been tracked. One can only hope that this increased consciousness would help people to choose services that don't track people. For example Hacker News doesn't need tracking cookies nor a cookie popup, and it seems to be doing just fine, even in terms of the law ;)
