Any argument is good, we already know that. We have seen enough from the RIAA to know they'd even use their own Mother as an excuse to promote their crap, only they ain't got no mother.
Here is the only solution for them. Kill off everyone. That way you won't have any piracy claims.
For those with half a brain, follow the logic through... Lets pretend everyone is dead cept those who are considered good customers.
Would they notice any difference? See problem already solved. They can't claim dead people stole from them... oh wait they probably can and have.
