But the fact that they won't accept new international customers sure makes it seem like they're discouraging international business, and I think that's not a very good sign for us.

I read that passage you quoted, and I think you are interpreting it too strictly. To me, when I read a phrase like "our international customers" they aren't specifically referring to people who have ordered in the past, they mean "any international person in a country that we service." They're just being polite about it by using the word "customer."
