Hanlon's razor is not a good heuristic, I don't know why everyone is so into it. If there's a monetary incentive to be deliberate, it's way more likely to be deliberate. Deception is everywhere, especially in sales.
There is plenty of malfeasance as well, as things have gone off in ways they didn't anticipate, RH and the other exchanges are making sure their big money clients are protected as best as possible from the WSB craziness at the expense of retail investors.
But the last bit wasn't planned which is what I was getting at.
