I've seen similar stuff in a couple of other places, including IT back in the 1990s (back when it wasn't nearly as glamorous as it is today).
I think some of this has to do with... resentment? You're this incredibly smart person, you worked really hard, and no one values you. No one wants to pay you big bucks, no one outside a tiny group knows your name even if you make important contributions to the field. Meanwhile, all the dumb people are getting ahead. It's easy to get depressed, and equally easy to decide that if life is unfair, it's OK to cheat to win.
Add to this the academic culture where, frankly, there are fewer incentives to address misbehavior and where many jobs are for life... and the nature of the field, which makes cheating is easy (as outlined in the article)... and you have an explosive mix.

Part of it, too, is that, while no one goes into academia to get rich, people quickly find out that the academic world runs on money. If you don’t get grants, you die, even with tenure. So what’s the point?
The reality of academia is so dismal that most people, by 30, wish they had sold out and chased money like the dumb-dumbs, who are, as you correctly note, farther ahead.
