I don't understand this, though. It seems to be driven by a misunderstanding of how the data is being collected in the first place. It isn't some security vulnerability with Facebook. And Facebook isn't distributing the data to a third party. It's just sharing the data with users, who are then passing it off to the third party (intentionally or otherwise). It's like expecting keyboard manufacturers to sue developers of keylogging software.
