> They remain the property of whoever issued it. What exactly do you mean by this? Licenses like the CC suite, and the GNU GPL or MIT software licenses, cannot be revoked after the fact, nor changed. The licensor can choose to stop publishing a work under, for example, CC, but all those who still have a CC licensed copy of the work may continue to use it according to that license. And in fact, I believe they can even continue distributing it themselves, making a license change mostly useless (unless the work is updated I guess).
