    Google, Facebook, Amazon and Twitter are 
    monopolies and should be broken up.

Dominant market share != monopoly

For a monopoly, you need anticompetitive practices. Is Facebook unfairly preventing the success of other social networks? A good example of a monopoly was 90's era Microsoft, which prevented its OEMs from shipping competing operating systems.

Terminology aside, I completely agree with you that we need far, far more choice in the marketplace.

Granted these are just lawsuits at the moment and not final verdicts but still it's not hard to see how they don't play a fair game.
