Absolutely. And, having done some agile consulting long ago, I'd say it's more pernicious than that.

The people who truly want to make deep change in pursuit of deep improvement are a small segment of the market. Worse, they don't need a lot of help. In the aughts, I had a few clients who really got it after 3 months of focused work, and then they were off and running.

But a large company that only wants to talk about change and maybe make some 5% improvements if they aren't too hard? That can be milked forever. Well, I can't, because I care about results. But consultants who either don't care or don't notice? They're golden.

And I think this failure of the Agile movement has been obvious for a decade. I gave up on Agile conferences circa 2009, and wrote a long piece about this in 2011: http://agilefocus.com/2011/02/21/agiles-second-chasm-and-how...
