One of the important things to remember about the Innovator's Dilemma is that it arises because smart companies are doing what they need to do in order to succeed. It is a reason why well-run companies fail, nota pitfall for bozos.
In particular, one of the reasons why low-end, disruptive technology gains market share is that the established players don't want that segment of the market. It's usually a commoditized, cost-sensitive business with terrible margins. The established players are willing to leave it to the disruptive innovators because it isn't worth fighting for.
