I don't really wanna defend King.com, but I think you're being a bit uncharitable. They talk about the community "creating tutorials, by finding bugs, improving the documentation". It's just tautological that you'll get more bug reports the more users you have, and creating tutorials/refining documentation are particularly suited to crowdsourcing (as the designers are often too close to the application to understand what a newbie needs to know).
And how is that a bad thing? You're missing the fact that people "testing" it are consumers, meaning any improvements will benefit them as well. Sounds like a win-win to me.
