No one is requiring Facebook share data, though it could easily be argued that they owe us. It's users who install a browser extension that are sharing the ads they were shown. If FB wants to serve people ads, why should they get to stop them sharing those ads with researchers / whoever they want? They claim the FTC is forcing them to, even though the FTC has stated that's untrue. This is fairly open and shut. Facebook are full of shit, quelle surprise.
