This is part of the reason why industries and governments are trying to get rid of the personal computer. It obeys us and not them. If we decide we want to violate some contract, the computer will make it possible and there's nothing industry can do about it. If we decide we want to encrypt some data, the computer will make it possible and the government will just have to deal with it or become a tyrant that assumes we're all guilty by default. If we decide we want to make "unauthorized" copies, the computer will do it without a care in the world about what some stakeholders think.
We have the keys to the machine. It is obvious why they want to take it away.

Personal computers definitely got in the way of the artificial scarcity, personal information collection, advertising and other harmful and exploitative experiences. Hopefully it will get in the way of even more.
