> What is the rationale after these changes anyway?
Development of new features for libstdc++ has already moved away from gcc.gnu.org to avoid the copyright assignment. Other contributors have expressed a desire to do the same. >From the GCC mission statement: - Other components (runtime libraries, testsuites, etc) will be available under various free licenses with copyrights being held by individual authors or the FSF. So that cannot be the rationale for this.
