Heresy!

How dare The Register mention anything about P2P software, even in passing, in anything less in glowing terms?! Don't the know that the great goddess P2P is the most powerful of all internet gods, bountiful supplier of 'free-stuff' to all her children?

You must be punished for this heresy!

The same principal applies to P2P software as does all software. If the user is in the habit of doing stupid things with the software then it is fault of the software. People are stupid, we know this, therefore it is the required spec of the software that it should be designed with this in mind. If P2P software is in the habit of catching out users, no matter how dumb you may thing they're being, then the P2P software's design is flawed.

Personally, I think you need to be mad to let most P2P software near your computer.
