My point is EU will adopt regulation that actively harms competition (such as GDPR), because they have different priorities (e.g. privacy, data ownership as you mentioned).

So to me it seems unfounded to say EU cares about market health and is not, in fact, just picking on FB and Google.

I am honestly curious what you think are examples of EU mechanisms fostering healthy markets. Maybe the MS case but that is the same “EU picks on US tech giant” genre.
