I think the author understands the depth of this acceptance of Agile when he writes:

'Today they’re surrounded a vast army of scrum-masters and evangelists, recycling (competently, mostly) the same insights, and an even larger crowd performing half-assed renditions of steps learned by rote: “Yeah, we do agile. We have a standup every day.” Many of these renditions have the professionalism, but not the passion, of a small-town talent show.'

Which may be my favorite bit in the article.
