Maybe so, but does a Facebook app uploading my phone number from a friend's phone to their servers, or turning on my friend's microphone while we are having an otherwise-private conversation, count as "freely posting"?
But I can't see a situation in which Facebook turning on a mike to record conversations is not a huge violation of privacy.
Do they do that?
Do they do that?
FYI, this is mentioned in the article. It also linked to this article on that specific issue:

Short version: It's not as simple as "they record all your conversations", but yes, they can and do turn on your phone's mic.
