Sure it is — they could let you run hooks from within class components. Not only do they not allow that, they actively discourage you from writing class components in the documentation.

Even if they didn’t have control over that, though, how does the complaint feel unfair? When I buy into a tool, I’m buying into the ecosystem as well. If the ecosystem moves in a direction I don’t like, that’s a strong disincentive to using that tool!
