Yet it's good to acknowledge that a small number of companies like Google, Facebook and Twitter are in practice controlling the media consumption of a large (growing) amount of people. They have the power to make fine tuned adjustements in how people perceive the world. It's fully voluntary and people gladly do it because it's so convenient. I don't think that the majority of people will ever perform their searches on multiple search engines to compare their results, in the same way they might buy two different newspapers or watch two different TV news broadcasts. So I think it's a completely new kind of monopoly on worldview, and that the old rules and approaches on dealing with anticompetitive behaviour won't work.
