Here is what Facebook has to say about this hoax:
There is a rumor circulating that Facebook is making a change related to ownership of users' information or the content they post to the site. This is false. Anyone who uses Facebook owns and controls the content and information they post, as stated in our terms. They control how that content and information is shared. That is our policy, and it always has been.
