He answered the questions the only way you can when lying to congress is illegal - only answer things you know 100% for sure are true, don't volunteer any more information than asked. Not to mention, the people asking the questions weren't seeking the truth for the most part, they were seeking soundbites and "gotchas" for political gain.

If you have to dodge questions and lie to avoid making your company look bad, it's probably a sign that you're doing something you shouldn't be doing.

This looks even worse coming from someone who runs a company that seeks to destroy the concept of privacy for the entire population (or, at least, the portion of the population that can't afford to buy the houses around their own and build 6 foot walls around 750 acre Hawaiian retreats for themselves like Zuckerberg has). The hypocrisy is incredible.

It's quite easy to make anyone look bad by questioning.

"Sir, do you know how fast you were driving. Were you aware that the speed limit is 55 mph? Do you know that hundreds of children die every year from drivers like yourself who value their own time over the lives of others?"

It's really easy to blame everything wrong with Facebook on Zuck. I can't fault him for doing his best to protect the company he built. I don't endorse or commend the shady business practices that happen over there, but I also can't fault him 100%. If you were put on the stand for a company you built, would you throw it under the bus for your principles? I don't know if I can say I would - especially in a high pressure situation like that. Let alone the amount of whispering in his ear from everyone his "team".

I think part of the issue is that his company, the one he's supposed to be leading and is fully responsible for, got to a point where he would be pressured to throw it under the bus for his principles. If he was a good leader, it shouldn't have gotten that far (unless, of course, what happened with Facebook was actually in line with his principles).
