And it means that someone would have to make a willful act of theft of IP, and that person would know full well about possible consequences. Like Christopher said, there is a big difference between finding a wallet on a street vs. taking a wallet from inside a car, even if the door was unlocked.

New format also provides both public and private metadata embedded in the WOFF header. If someone decides to download a font from one server and upload it to another without modifying the metadata - it would be like stealing the bag of money with the spray paint inside. He would just announce to the whole world that he is using stolen resource. And if that hypothetical someone does make an extra step of modifying or removing metadata - that would confirm to the world that theft of IP was in fact the willful intent.

Did anyone ever mentioned that same-origin restriction should be limited to fonts?
I agree with you, it makes perfect sense to protect resources (and the bandwidth the rightful owner of that resource is paying for), but it is not something this WG can solve. However, developing a new recommendation for Web fonts is the WG charter, hence this discussion and application of same-origin restriction and CORS for fonts is perfectly reasonable and appropriate, IMHO.
