If somebody gets access to your system, they could use that to blackmail you, and/or frame you for distributing said media.
"Give us $X, or we leak and distribute Y media on your behalf, and you will get sued by the corporate goons for shit loads of money"
The only real solution is to completely overhaul IP law, and/or nationalizing funding for the arts. If we're gonna keep corps that own/produce media, then they should have a very short and limited amount of time to distribute it before it becomes common property of the people.
