The form of the meeting gave no chance for more than fleeting cross-questioning and ensured that while sharp questions could be asked in plenty Zuckerberg was free to respond with loose generalities and was never put on the spot.
That is the point I think, let him show his commitment or his lack thereof.
He did answer the spiky questions by ignoring them. (I know a real answer would be more useful to us, but I believe that what most interested MEP were Zuckerberg intents)
I think they were interested in getting answers from Zuck but with how the session turned out, I think most of them have most of the answers they need even if Mark didn't speak it out loud.
