I moved nothing. You didn't read my original comment that clearly specified "real world attack". Your second link doesn't qualify either. Besides, if you can connect a malicious USB device to the user's computer you've already won. There are a million ways to exploit that which have nothing to do with Chrome.

The xz thing was a big deal precisely because it was a real world attack. It wasn't something created by researchers as a proof of concept and disclosed to vendors. It was discovered in the wild, luckily before it caused any damage, but it was absolutely a real world attack.
