What evidence is there for that though? It sounds to me as though it's free market dogma posing as reasonable common sense. In social media, for example, there is currently competition. Yes FB is big, but new players are entering the market and causing them to shrink precisely by making the web even more toxic and unpleasant. Perfecting this process and introducing more competition (read desperation among product managers in the losing firms) isn't something I want to witness.
