The scandal is much bigger, in reality every APP of the Facebook platform slurped data!
In reality every Facebook APP using the API v1 had access to all of the FB users data, and access to their friends data as well. But the scandal is even bigger. FB apps had permissions on iOS and Android to read the users phone book, SMS, photogallery, and uploaded all data to FB cloud (not visible to the user, but analysed). And Facebook creates shadow profiles of those contacts that have no account yet. Websites with embedded Facebook "share buttons" and Facebook comment sections track web surfers and create & update those shadow profiles as well. So it's not about 85mio accounts, it's about 2 billion accounts multiplied by the number of FB apps using API v1. suckerberg..
