Cool. So, how does this impact consumers that never used Facebook, but that have shadow profiles for social network inference and ad tracking?
Presumably, since Facebook has no way to contact those people, they will just shut down the no-logged-in-but-tracked half of their business in Europe?
(If you don't know what I mean by shadow profile: When you first create a Facebook account, it helpfully produces a prepopulated list of your friends, and links in a pile of consumer tracking data before the onboarding flow is done.)
