What freedoms are gained from using Apple devices? Freedom to purchase things from Apple's app store? Freedom to install iTunes?
Do you equate freedom with empowerment? I do agree that Apple's devices have empowered people. But freedom and empowerment are not the same thing. You have more freedom to modify and adapt a post-it note than you do an iPhone.
The freedom issue is whether people have control over the machines they invite into their lives. Especially recently, Apple's devices force you into an (arguably exploitative) dependency.
Apple devices give you freedom to not care about your device.
And your distinction between freedom and empowerment is a false one in the real world. Freedom is generally about empowerment. Apple devices give you the power to exercise your freedom -- except along this narrow axis that you and Stallman seem to care so much about.
So why can't they give you freedom to root your own device or sideload your own apps. The 'safe garden' is still there for those who want it, and those who want more could do that of their own accord as well. Apple are unnecessarily restrictive.
