It's called PR. I'm not sure why you take it for more that it actually is.
Besides, it's not only the Winter Olympics, a good chunk of the summer disiciplines are also a western club + friends (rowing, track cyling, sailing, etc.). Every olympic sports come from the west. A few have taken off globally, most didn't (often for la ack of infrastucture). You may find it sad, unfortunate, but that's not going to change anytime soon and I don't think the IOC is delusional about that. Then, you have PR...
If they were really looking for global integration, they would include Kabbadi, not skateboarding.
