They have enough power to behave as a small form of government. They use this power to accept political lobbying (aka bribery, like to government) to enact regulation (like a government would) to ban businesses their lobbyists don't like.

This can very easily slaughter businesses. These companies need to be regulated as a utility instead of the insane shit that's happening now.

I hope more people start understanding that unregulated big business acting like unaccountable government is a problem.
