This article has 0 insight. This was the most strategic answer. - A: facebook does a lot of things and it's true it competes across many categories

- B: Admitting competition is bad for wall street, legitimizes them, and turns the narrative into whether that is true or not (you don't want that to happen either)

- C: The senator was obviously trying to bait Mark into saying that they have no competition... why? Easy anti-trust/regulation. He avoided that as well.

Mark took the most strategic path. Sure - it could have been delivered better.
