Every work of fiction is "nonsense", but they still have value as entertainment and story-telling. The difference is that fictional works are understood by the reader/viewer to be fictional.
The problem with nonsense that purports to be true is that there's usually a scam attached to it, to separate people from their money. Fictional stories don't have this: everyone knows they're fictional before they spend their money on it, and they know what to expect from it (i.e. pure entertainment, not a cure for whatever ails you).
Luckily for us software development is a completely rational discipline, and is immune to fads, fashions, rhetoric, snake oil, and beliefs with no empirical foundation.
Nonsense spreads not just because of apathy.
