Talk about wanting your cake and eating it too.
It's not just the uploading of videos so that they could sue, it goes well beyond that.
It's uploading the videos so you get free advertising, it's uploading your videos so you get free press when you decide to sue, it's uploading the videos to boost ratings and viewership.
So now instead of thanking Youtube, you turn around and sue them. Great plan, too bad it's coming back to bite them now.
