any more questions?
Who's worried? The only thing to worry about is that the company might place their protection money at a cost below the lawyer's fees for the defense and therefore make it cheaper to pay them off (even if they have no legal case) then to fight it. The EFF is involved to bring the cost to fight it to effectively to nothing (at least for party with standing).
Who's making a fuss? Righthaven is making a fuss. Mr Allen is making a fair use defense. He's making a number of other defenses too, there's the I didn't post it and you should be going after the person who did defense and the you are actively asking everyone who visits your site to post this to other sites defense. There is also some amusing arguments as to the proper name of the plaintiff's counsel, but really the most important one is the fair use defense.
Characterizing a quite proper fair use defense as "stomp your little feet, spit out your dummy and DEMAND your RIGHT to freely take other peoples stuff" easily exceeds the bar of "maligning the doctrine of fair use."
Feel free to come after me for "freely taking your stuff" by quoting you for the purpose of commentary.
