Yes - and it's also true for many DevOps people. Some would argue that's even true for many managers. It's just not a good idea if you want to get where these people where supposed to get you when you hired them.

I’d say that is absolutely untrue in the case of agile.

Those promoting scrum (and especially those with certifications in it) are going to lead to scrum, not an agile process that values producing useful, working software each iteration.
