>I never tell stores who I am. I never let them know. I pay cash and only cash for that reason. I don ’ t care whether it ’ s a local store or Amazon — no one has a right to keep track of what I buy. The local store, I might do business with, I wouldn ’ t give it any way to know my identity. I would pay cash. With Amazon, I can ’ t pay cash, so I don ’ t buy from there.

>And secondary features, conveniences and so on, should not be allowed to justify making the primary goal require collection of data. Let ’ s say you want to ride in a car and pay for the ride. That doesn ’ t fundamentally require knowing who you are. So services which do that must be required by law to give you the option of paying cash, or using some other anonymous-payment system, without being identified. They should also have ways you can call for a ride without identifying yourself, without having to use a cell phone. Companies that won ’ t go along with this — well, they ’ re welcome to go out of business. Good riddance.

>We need a law. Fuck them — there ’ s no reason we should let them exist if the price is knowing everything about us. Let them disappear. They ’ re not important — our human rights are important. No company is so important that its existence justifies setting up a police state. And a police state is what we ’ re heading toward.

>Most non-free software has malicious functionalities. And they include spying on people, restricting people — that ’ s called digital restrictions management, back doors, censorship. Empirically, basically, if a program is not free software, it probably has one of these malicious functionalities. So imagine a driverless car, controlled of course by software, and it will probably be proprietary software, meaning not-free software, not controlled by the users but rather by the company that makes the car, or some other company.

>Well imagine if that has a back door, which enables somebody to send a command saying, “ Ignore what the passenger said, and go there.” Imagine what that would do. You can be quite sure that China will use that functionality to drive people toward the places they ’ re going to be disappeared or punished. But can you be sure that the U.S. won ’ t?
