Didn't facebook get away with doing that exact thing with whatsapp? They promised not to combine the phone number data with their other data and did exactly that. Maybe they got a slap on the wrist fine.

Yeah, it'd be good if the governments that had issues with it changed their position to require divestment of WhatsApp after facebook pulled that shit.

Pity that didn't happen, so yeah... they got away with it. :(
