They care about expanding their audience. Justin Kilar talked about this in his interview with Charlie Rose. The problem arises from the legal complexities of differing cross-border ownership rights. Hulu has to get permission from the content owner and in many cases the content owner in America will be different than the owner in France (or whatever other country). In addition, they then have to work through the regulatory frameworks there. So it's not a matter of not caring, it's a matter of overcoming the legal hurdles.

From what I recall, Kilar's intention is to first try to expand into China. An admirable goal.
