|Subject:||Not "Free Mickey"|
"Free Mickey" doesn't give the sense of a larger problem. A good phrase should somehow give the impression that the problem is permeating throughout society; it isn't limited to a corporation's mascot.
Furthermore, the phrase says more about "Mickey" being in chains, instead of us. We're trying to unshackle ourselves, not help a corporation, which is the sentiment implied if you don't know much about the topic.
