This equates power to freedom, where the degree of freedom correlates to the degree of power, and only the truly powerful are free. If that is your thesis, then you are in agreement with Snowden.
More power draws more responsibility so not necessarily. Yes, you have more freedoms as in choosing what to buy but material freedoms are only one branch in the many freedoms one can have. So I can agree with OP in that ability of one to manipulate power for freedom is a good definition of one's true potential for it. One can also give away certain powers or responsibilities for more freedom.
