My belief is that, fundamentally, everything should be open. Users should have full control over their devices, and manufacturers should have no place in dictating anything about how they are used, what software can and can't run on them, etc. (Note that I'm not being anti-proprietary-software here; I don't think companies should be required to give away their source code if they don't want to.)
I get that this isn't relevant from a legal perspective. But so what? I can talk about where I want the laws to go.
