True but that's a different problem. As long as companies are allowed to consolidate just this short of obtaining a monopoly that kind of problem will remain. You'd have to address that separately for it to be effective. That's why you always see a lot of competition in a new field which eventually crystalizes out to two, sometimes three main competitors that all have double digit marketshare. It's why we still have Apple and Mozilla. But from the point of view of the would-be monopolists those are optional.

I far preferred it when we had a more diversified eco-system and long run I think we will come to regret this monoculture.
