Cognitive dissonance? I think those who claim that IP's aren't identity would still claim that with regards to Warner Brothers. It's just delightful schadenfreude that claiming that it is identity would now implicate Warner Brothers. You can still believe the first while thinking the second is humorous without any doublethink.

In case this doesn't reflect my views re:piracy/copyright; I think that it's ethically wrong but the greater crime is disproportionate lawsuits, inappropriate DMCA takedowns, and lobbying for laws that remove freedom of speech from the internet.
