Water "wants" to flow downhill. Gasses "want" to expand to fill their container. Genes "wanting" to replicate drive animals literally wanting to reproduce, and the incidental awareness of that drive in some species comes down to a certain molecular arrangement brought about by said genes. The genes are data, the minds are data, and the natural pressure is that that data which succeeds in reproducing will tend to keep reproducing. So in the original sense of the notion of memes as proposed by Dawkins, yes, information "wants" to be free, as that is its tendency. The only other option is that said data ultimately dies out.
