"4. The internet itself is destabilizing the entrenched markets."
This one is a bit unfair, though I don't know about the rest. "The Internet (TM)" doesn't just destabilize industries in an abstract sense, it destabilizes them by a set of real companies that take market share from entrenched competition, and by allowing that entrenched competition to sometimes improve themselves in the new market (which doesn't happen as often as you'd think). It's not "The Internet (TM)" that gets credit, it's those companies.
