> Different laws apply to companies in a monopoly position,
That doesn't necessarily mean the same thing as "used by the majority of people", since people can and do use many different sites rather than choosing one exclusively. Those laws also doesn't have anything to do with the absurd schoolyard notions suggested by the comment I responded to; monopoly laws exist primarily to keep monopolies from preventing others from entering the market and disrupting that monopoly.

In your opinion; I strongly disagree with the notion that such laws have any basis in morality.
