I have, and I don't entirely agree. Unfortunately, I haven't read the actual complaint all the way through... but I trust Tim Wu, he's a terrific attorney and Intarwebz Fella, and I think this is the right case here: http://www.slate.com/id/2181776/

I love and adore J.K. I think she's trying to do right by her material. I think Steve's been a real jerk, and he really really could've handled this better.

But I think Tim's got it straight; encyclopedias are not adaptations, they are an entirely a fair use.
