At this point, I think that regulations are useless. Not because these companies aren't harmful. But because they will either convince the government that they'll self-regulate, or they'll use their insane profits to bribe the politicians into castrating the regulatory agencies. I'm convinced that the only way to prevent these greedy scum from harming humanity is to never let them grow that big in the first place. When these companies are big enough to control the government, they should be cut down to size with a healthy margin of safety.
