"Unnecessarily political" is a nice abbreviation of "his politics are hurtful, hateful, and part objectively wrong".
I'd say the same about Stallman's page for instance, or Torvalds', and their politics are drastically different
entering in value judgments on the specific politics is a fool's errand - I think he's doing good work, and thus the politics are counterproductive as they take nearly all the attention away from their work
