How about asking questions like: What sorts of speech will get me banned on Twitter? Do you think you've done enough to turn Twitter around? Why is Facebook so successful while Twitter looks to be in trouble?
I'm sure the interviewer knew of these topics but choose not to. For reasons I can't speculate on.
Those seem like pretty awful questions imo. He's not going to waste time listing off things that will get you banned from Twitter. He'll tell you not to violate TOS (in other words don't harass people). This should be common sense. With your second question he's obviously not going to say no. He'll give a standard PR reply. Same goes for the third. He's not going to talk up a competitor.
It would be common sense if the ToS weren't selectively enforced based on how far one strays from political opinions that Twitter finds acceptable.

To be clear- I am not sure if I believe Jack's denial or not. This situation appears to be a big opaque mess to me.
There's a lot of real questions that could have been asked instead of "How will you have improved yourself in 10 years?" which nobody can really answer.
