IANAL, but I think this is wrong. Unless the license stipulates that the terms can be changed by the licensor, then the licensee only has to abide by the terms from when they agreed. The GPL goes out of its way to make it possible to use licenses from before what's currently available: >If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation.
