no no no that's not how any of this works.
first and foremost facebook will reassure its users and regulators that they will uphold consumer privacy and won't share the kyc info (id, address etc.) for ad targeting on oblivious users. they will do this in the most legally binding contractual way possible called a "pinky swear declaration".
then when no one's looking, they'll share the info, get caught, declare a "leak", get fined and say "oops it was unintentional" (exactly what they did with whatsapp).

haha... oh wait they are serious BWAAAHAAHAHAHAHA!
who's dumb enough to believe respecting consumer privacy is even possible for a platform that profits from ad targeting? besides i seem to remember them making a similar promise after the whatsapp buyout. which they broke after a few months.
facebook acquired whatsapp in ~2014, said it would not (and technically could not) combine whatsapp data with facebook's data and then proceeded to combine the data anyway. this allowed info like phone numbers to be used for targeted advertising on users.
facebook went "oops, we screwed up when we said that but it wasn't intentional".
