I tend to agree with them here, but the thing that always gets me is how many people will support these same actions if, instead of being done by the elected government, they're done by unelected internet companies that hold monopoly power.
I get why that may be more of a problem legally, but not why so many people agree with it morally, because they come from people not otherwise inclined to agree with the proposition that a monpolist's business decisions are somehow above scrutiny.
