Facebook also doesn't sell personal information to advertisers. Both Facebook and Google let advertisers target ads based on location and other personal info, which is not the same thing as actually providing that information to third parties.

I suspect JumpCrisscross is referring to the data leak scandals via the API that have been in the news in the last year. Of course, this was also not Facebook selling information. Rather, it was Facebook allowing users to share information about their friends automatically and without the friends' consent via the API. Not great, but not selling user information either.
