what happens if I put the gun in your hand, point it, put your finger on the trigger, tell you to pull it.
Hey, you're the one who shot that guy, and I have a disclaimer to waive me of liability? I don't think so.
See, it's not my gun though. It is YOUR gun that YOU bought (downloaded yourself). I just teach you how to load a bullet into it and promise to clean the floor after you're done 🙂. You're paying me for knowledge (no different than you would pay for in a book, Im actually giving the Mac knowledge for free though), and the service of cleaning up after you're done (This is what i charge for).
btw, I would never tell anyone to pull it, I am just telling them HOW to pull it (big legal difference, and this is what protected many of "How to be a terrorist" books under free speech).
