Typekit understandably wants to make sure that no one else uses the font bundles, so they check the referrer. If you strip referrers it'll block the response and eventually it'll timeout, and show using the default system font.

The choice is a delay for the few people who block referrers or a flash of unstyled content for everyone else.

Ah, I see. Quite silly in my opinion but thanks for the answer. I'm fine with how it is -- there isn't a reason to protect the minority in this case: bigger fish to fry. :)
