Participant, thinking in Europe is that it is the role of the government to censor, not private businesses. So this is more of a European approach. I do not deny irony here.
Maybe a business perspective is better: first amendment works when we have a “marketplace” of ideas. We seem to have a monopolistic structure right now, with several large companies dividing a market to minimize competition. Starting new media is a good approach. But it is pretty hard to break monopolies. so, then government regulation is in order.
