Well I think you hit the nail on the head, that the disclosure isn't responsible. I'm all for bringing the flaws in chip-and-pin to the public attention, however I find it distasteful that a leading university publishing the schematics of a device that can be used to commit fraud, receives so much applause for this community.
I get the impression that this has captured the public mood of "sticking it to the bankers", when really Cambridge have gone about this one the wrong way.
