The questions asked by the parlement (and the US senate) to Mark Zuckerberg show very clearly how minimal knowledge politicians have of the reality as percieved by 'the rest of us'.
I watched the entire zuckerberg united states senate testimony and I found much of the questioning incisive and valuable
Honestly a fair number of quality questions were asked and deflected by Zuck, and he knew how to play some moments to make the senators look stupid for those social media soundbites. But to be fair, an alarming number of questions were also either very poorly formed (intention was there, a millennial proofread would have helped though) or were thinly veiled self indulgent political maneuvers. Zuck actually did a good job defending net neutrality at one point where the line of questioning was obviously a nod to the ISP cabal.
