As I recall, there was more than enough evidence being put forth in this case that showed that not only was viacom totally blind about the facts of their own case but their companies were even using youtube to promote their "copyrighted" material in the form of video clips and partial (maybe full) episodes.
There is a double standard. It's only infringement when the poster isn't the owner yet there are plenty of posts by the owner and neither path providing proof of copyright or a release to rebroadcast but then expecting youtube to know the difference between what's legit and what's not.
I don't buy the "service for infringement" rule. A law is broken by the lawbreaker and no one else. Providing a service that has legitimate and legal use doesn't break any law even if the use of that service become mostly illegal use. The legal issues are still on the shoulders (or at least should be) on those who do the actual crime. If suddenly no one bought Ford trucks except those who transport drugs, is Ford suddenly a criminal corporation? No.
As for you doofs that always complain "it's U.S. law, not .." Try reading up on "International Copyright Law". Ever read the warning at the beginning/end of a movie?
Try this:

So, while it may be that U.S. law isn't your law, there are still laws that apply equally to the U.S. and a lot of other countries too.
Personally I'm a believer, as I am a software developer, that infringement is between the owner and the infringer.
I have a saying "It's not an issue until it's an issue." In this case, if the copyright owner doesn't sue, then no one else cares about it... It's not an issue for anyone until it's an issue for them. Then you have to duck and cover. Until then, everyone else couldn't care less about it.
