I'm doubtful about this narrative as well. Unsurprisingly, it's a conspiracy theory with no evidence. Good old Bill Bonner.

I'm not sure how you mean the Bonner name-drop, but fwiw I first started mining
BTC early in 2011 because of endorsements by Bonner's then-associate Joel Bowman. Bonner has been fence-sitting of late, with his company often endorsing crypto-pumper Teeka Tiwari while Bonner himself muses about volatility - I think he's a gold bug at heart. Anyway, this particular article was written by Dan Denning, not Bonner, and Denning's stuff often turns up on conspiracy-oriented sites, for whatever reasons.
As for causes of the current crash, I have no idea but enjoy the stimulus of trying to figure it out. Back when
BTC was worth pennies or a few dollars, the real-world effects of the volatility were trivial. Now large paper fortunes are made and lost, so in that sense this one is the most alarming yet.
