I hear these aphorisms a lot, but none of it actually matters.

Agile has been plastered over certifications, podcasts, books, conferences, trainings, and everything else for years. The people I referred to above had been through it all and brandished it like a weapon. You can tell me all day that it's not true agile but it didn't make an iota of difference to how things play out.

Judging by the comments, my experience is not unique.
