Stating the problem in this way is not very useful. Nobody would like their device to offer absolutely no privacy (e.g. everyone can browse your filesystem), absolutely no security (publicly available shell), or no freedom (every command or action needs third party approval). A certain amount of each is essential. A better question would be how much of each is a hard requirement for you and how much is merely nice to have.

All three are indispensable and interdependent:
- How can we know it's truly private unless the code is open and free?
- If your identity and data isn't private, will you be able to exercise your freedom without fear?
- How can your data be secure if it's not private?
