I find those warnings hilarious. I also admire the fact that the Internet, an entity the corporations believed was going to double the percentage of the gross national GDP they took home, has severed and urinated on the hand that funded it.
Sure it's stealing, sure I have no right whatsoever to the intellectual property of Dr. Dre, Pepsico, Mr. Jack Daniel's or anything except the play I wrote back in primary school, sure there's no real moral argument for my actions. But, let's face the truth for a moment, it's fun and on some level it feels like you're getting even for some crime you can't even name.
The RIAA are scared, they can't prevent P2P filesharing and that good ol' greed that drives the real core of the human heart has surfaced to take advantage of that.
God bless you, Internet.
P.S. I love that advertisement, it reminds me of the "Kill your speed" advert that actually caused me to drive with even more manic glee. Also, it's good to see the RIAA never prosecutes anyone fat or particularly ugly.
