I figure that's temporary, though. It'll go the way of Napster.
Actually YouTube recently signed a deal(Right before Google bought them) that made it so they can legally host WB's music videos, and I believe since then a few other studios have jumped on board. In return they get a cut of the advertising from while those videos are being played.
As such, it may rapidly become a new method of delivering content legally, and finally may be a step in the right direction on the part of the RIAA/MPAA instead of trying to sue everyone and their dead mother too.
Unfortunatly though that may have mixed results for Linux if things don't improve for our support of flash on it.
