It's because none of you (ok, maybe most. Probably not all) have any idea what you're talking about. "ThePirateBay" as an entity didn't DO anything except make themselves open for user content submission. There was no moderation on anything, and users were not encouraged to upload illegal or legal content. The Pirate Bay was being sued for "helping people conspire to commit copyright infringement," which barely sounds like a crime, as file hosting companies like Rapidshare could be sued on the same grounds. I'm still not completely sure what part of the law allowed them to be found guilty, and who specifically bribed the judge to produce that immense and unfair fine, but there has to be some corporate trickery going on somewhere.
Ebaumsworld blatantly steals content from other sites. I don't think it is very legal, but the large corporations and lobbyist groups probably don't see it as such a large revenue loss for them as the Pirate Bay was, when, ironically, most of the content that would have been on the Pirate Bay will show up somewhere else, as it's user-contributed, whereas shutting down Ebaumsworld would have a much larger effect on the general populace of file-sharers.
It's a complex topic. Sorry if I didn't make sense.
