It was a bit of irony, but apparently it went over some heads.
In fact, my problem was with the sarcasm.
Once you publish something under copyright, you have declared that the material really does belong to the people.
These aren't dirty, smelly hippies that want to squat on your back lawn.
These are people exercising their Constitutional right to a Fair Use exemption to copyright.
It would be like having someone sue you for using a Citizen's Band radio, trying to keep you off of those frequencies. And you suing right back, because CB frequencies are yours to use by law.
