I think the trees are really significant here because the other commenters are trying to generalize an instance that can't be generalized without discarding significant details. To give a concrete example of how that over-generalization is incorrect: Kay Cole James hasn't even been shut down. She's welcome to participate in the public discussion of AI and ethics. On her own platform. Over there. Which is what James has done in the past and is welcome to continue to do, without the implicit imprimatur of having her views taken seriously by an ethics board for one of the largest software engineering companies in the world.

Being barred from speaking is entirely different from being denied a seat at someone's table. Or are we also upset that The Heritage Foundation doesn't have Miss Major Griffin-Gracy on their experts panel?
