> The senator was asking whether facebook owns that data it has about a person, and the answer was that you own what you post. Those are very different sets.

It answers by exception; specifically, the answer is “Yes, except for information consisting of content posted by that user or other users, which is owned by the user who posted it.” I don't think the answer was at all unclear.

It's obviously couches in a way which directs the attention of the inattentive to the most user friendly component of that answer because it's the only explicit part, but minimizing the PR fallout is literally Zuckerberg’s job, so expecting him not to anything less than the maximum he can in that regard without lying to Congress is expecting nonfeasance on his part.
