"Enforcer" appears to be Bird, not 142. And as far as I can see he's not making a legal challenge or encouraging anyone to do the same, he's encouraging people to complain to the relevant regulatory body. That's his right and I wish him luck. Wikimedia is a serious organisation and can't be intimidated every time some disgruntled user calls the cops. If Wikimedia really was breaking the law (and I accept Jimbo's assurance that it is not), then that is a problem that I hope we would all be interested in seeing addressed.
The idea that Bomis has editorial control over Wikipedia sounds bizarre to most of us. Witness the edit war conducted between Erik Moeller and Tim Shell over [[Bomis]] in mid-January 2004. Bomis can't even exert significant editorial control over the article on itself, let alone an article about an advertiser on a blog which is linked to by Bomis.
And I'd like to extend my thanks to Jimbo for the extraordinary amount of time, money and effort he has put into Wikipedia. It has become a truly extraordinary resource.
