I'd call it "fixed" rather than "damaged" -- they did throw in that fuse
in case of "any defective ROM code in handling bad block marker byte
swapping", and the entire concept is defective.

But I agree that if you're delivering them to other developers, rather
than as part of a final product, they might want to make that choice
themselves. And who knows, blowing the fuse might expose other defects.

Probably not, but they should still hear about it, if only for the
chance they'll do it right next time.
