Beyond Disruption

The author isn't just stating the case of the word being misused, but to advertise his alternate model.

The take-away is that the new successful companies don't follow disruption theory, which is a bottom-up approach, but a different, top-down one.

It's importance is figuring out successful strategies for orienting and managing a business: don't undercut the competition, start with a niche that's willingness-to-pay is higher.

As someone who hasn't read much on management theory, it was illuminating for me.

Diction is also important, but that's a whole separate conversation.

It isn't just a word. It's a fully articulated theory of business management. Books, papers, articles, speaking engagements, &c. For many years, it has been the in vogue startup model.

TFA argues that there are newer, often better strategies to consider. It's a good argument.
