I understand that Wikileaks is controversial but I don't think there is any dispute that he has acted in the role of whistleblower to some extent. But that's not really the point I'm trying to make, so I've removed the reference.
I think I'd argue for a sui generis classification, which does partake somewhat of the whistleblower, but it seems like calling Napoleon a general. He was certainly that, at times. Apologies for the nit-picking in any case.
