Yup, crunch sells books. Plus, GMs are under no duress to use anything from any particular book in their personal campaign, so if you don't like it, don't use it. If a potential player has a huge issue with it, they can find another game. I know that sounds harsh, but the truth of the matter is that players are far more replaceable than GMs. If you want to play in my campaign and I'm not going to allow Artificers, or Druids, or Elves, or whatever, that's just the way it is.
