I think if they control 60% of the news pipeline (and climbing), they're categorically different. The U.S. government regularly investigates similarly large entities.
Facebook, et al, campaigned to have internet access be considered a utility instead of a luxury. The UN is pushing it as a human right.
If you follow that line of reasoning, the companies who run the pipes and control the flow of information aren't just companies playing favorites. They're potentially influencing - if not outright regulating - human rights worldwide.. which means they should have a much higher level of scrutiny.
