If the goal is to provide liberty, as in letting people choose what to do with the code for themselves, then MIT might be a better choice. This really depends on whose liberty and what kind of liberty you have in mind. From a GNUish perspective, the MIT license gives you the liberty to... restrict downstream users' liberty to modify the software and distribute the modified versions. The GPL restricts your liberty to restrict other people's liberty in that manner. Which is more free in some kind of libertarian sense probably depends on what you consider the status of copyright in the first place. If you think the ability to restrict downstream users through the copyright system is a kind of natural right (perhaps by analogy to property), then the GPL is adding restrictions on your ability to exercise that right, and MIT/BSD licenses are freer. If, on the other hand, you think the ability to restrict downstream users' distribution through copyright is an artificial privilege granted by the State, then the GPL constraining your exercise of it is not really a loss to liberty.
