I was very disappointed with congress's knowledge of technology. They didn't ask the right questions, and kept accusing Zuck of selling data... which he doesn't really do.

What most fail to grasp is, once a 3rd party has your data.. it is literally impossible to "get it back" or "make them delete it". I don't understand how forensic audits work either- files are fungible... just because a company's computers doesn't have something doesn't mean there aren't copies. America needed to hear the uncomfortable truth: a TON of data about you is out there, more than you could imagine... and you can't do anything about it.

I wish they asked more about psychographic profiles, or how effective political targetting was, or why Trump had 5.2million approved facebook ads, 90 times more than Hillary's 66,000....
