Piracy for profit is clearly out of bounds, and always should be. On that we can agree. It is also easier to find: If is generates big profits, there is a bank account somewhere that can be siezed.
Where we part ways is this: I find the security of my documents and the ability to operate a machine I own as I see fit more important than anyone else's ability to profit from IP in the face of not-for-profit sharing, especially if the only way to stop that sharing is to install Big Brother Inside, even if it means the end of the RIAA and it's constituents.
