He's a good marketer, but one of the worst people I've read about. There's a file of his quotes (from the CCC mailing list) circulating, if you know german you should try reading that. Really gives some insight into him. For example how that l33t hacker cred he has is all for show– I wouldn't buy anything about free speech from him either. He's only interested in money. I remember one quote from one of his teachers about how Kimble was the most antisocial kid he ever teached LOL.
TLDR: You really shouldnt like the guy, read a bit about him and you'll figure out why.
