That's what makes it seem arbitrary and annoying. When you buy a low-spec chip, you get it cheap because it could be defective. But when you buy this, it's perfectly functional, just artificially limited. You aren't helping Intel increase their yield and getting some savings for helping them -- you are just being fucked because they feel like fucking you.
I hated Intel for a long time, but then they started making good products and contributing drivers to Linux... but if they keep this sort of thing up, that goodwill is all going to erode and AMD will have to opportunity to get the enthusiast market again. (Their "we'll sue you for using the HDCP crack" is similarly goodwill-eroding, especially because there is nobody they can even sue.)
