isnt this basically piracy enabling technology? its good n all that people take the stance they will only use it for their legitimately owned copies but thats not the reality. people dump stuff and spread it around, and others play illegal copies. its much more rare for people to use such tech legitimately than the other clearly illegal case...

Selling a tool designed to circumvent DRM, even to make backups, seems straightforwardly illegal under the DMCA? I'm not sure that counts as an abuse of the law...

Using it to shut down emulators that don't help you circumvent DRM does seem like an abuse, though.
