When you ask general questions you get "We did not do anything illegal, we did something wrong though; but, people do not read Terms Of Use/Privacy, and they do not read manuals"<p>When you ask very specific questions you get "I need to get back to you on that", right?<p>There is clearly a conflict of interest there. In a public hearing the CEO of his own company is basically forced into giving up their trade secrets on how and why his company even got so successful in the business of ad targeting.<p>The question is: In his place, what would you do? Tell everything and potentially break your own company, your system, life achievement, whatever? Or be careful and vague to save it? I'm not trying to defend his position, but rather to understand it. In any case, he maneuvered himself and his company in a situation where it'll be impossible to keep secrets anymore. Nothing will ever be the same, and he is responsible for it, because it was his idea and his intention behind enabling his company to <i>connect people</i> by selling ads.
