There's no need to quantify harm for something to be illegal, especially if it's something as difficult to control and evaluate as personal data.

I have a suspicion you're talking from a USA standpoint, where antitrust is enforced based on provable harm. This is not necessarily the set of values that the EU population wants to live by.

The Dieselgate was already deemed illegal, making your remark a case of whataboutism.

If you're talking about the recent fine, that was on the grounds of antitrust and unrelated to lying about emissions. AFAICT, the EU has yet to fine any automaker for the latter.
