This feels like peak Scott behaviour. He finds some alarming thesis based on pretty flimsy data, then proceeds to reorder his entire worldview around it. It’s basically the same thing as his belief that we live in simulation, except that only offends people who know anything about computer science.
Also, I find it kind of amusing that Adams seems to have actually managed to torpedo his little media empire, while J.K Rowling has basically no-selled being Internet Enemy #1 for years. I’m not sure if this says more about respective depth of fandom, gender issues versus race, or just Adams being a legit crazy person.
All these media companies dumping Adams are probably shooting themselves in the foot, though, or at least stepping on lego. Like, do most people who buy Dilbert collections even know about him being a nutjob, let alone him going all disappointed Elrond on black people? I suppose it shows that capital is willing to sacrifice some profit in order to signal ideological adherence to the right people.
