It clearly cares about non-English speaking people, as there's many articles in other languages. As I say, I don't think the vast majority of people consider wikipedia as a "community". They consider it a place to find facts.
However, you don't dedicate 90% of your home page to 5% of use-cases.
Is it that hard to have a small dropdown language selection in one of the corners? I don't see why "language" needs to be the main thing on the wikipedia homepage.
Also I'm not sure going forward that language will matter that much. Chrome can already translate webpages to whatever language you choose with pretty good results.
