Is everyone at Meta really just that fricken weird? Do you not work on this and go "wow, this is creepy AF"

Ugh.

Isn't this illegal under GDPR?

Definitely hoping all the fines (thinking of the $1.4T lawsuit also in the news) add up to more than the company is worth.

Not until they get fined pennies on the dollar in a few years and then spend more time in court fighting it until they are actually required to pay said fine, at which point it doesn't matter anyway.
