YouTube asking him to remove the videos doesn't mean he's being sued. Actually two of the four videos I had made were removed due to copyright claims on the music used. It's just YouTube's way of moderation...
I hope he's not getting sued, lord knows there's an endless supply of illegally used material on that site if that's the case.
I talk with him every once in a while. I'll ask him what's up next time I talk to him.
