While I agree that it's rather sad for developer not hosting their Wiki, I really never had any problem with the old hoster of the Minecraft Wiki. I certainly didn't perceive it as a "crappy provider". It did exactly what it needed to and there weren't any intrusive adds or at least not to my attention. But maybe I'm just really good at ignoring adds myself.

Edit: Or mabye my add blocker did help, hard to tell since I haven't seen the internet without it since years now.
