Do what we did in the past with monopolies: break them up. Trust busting to increase diversity and competition, just like the railroads of past. I would consider the advent of social media to be on the level of the advent of the railroad or the car. Same with search (Google) and even Amazon (mega online store with fast delivery). At the very least subsidize Walmart or some other competitor to build out a competitive advantage and eliminate Amazons head start.

Very disappointed we don't have a Windows phone as an alternative also. I think 3 is the bare minimum for a technology to have good competition. So why not.

My overall point though is the same, regulatory capture is bad and we should fight it regardless of monopolies or not.
