"But to be GPL-compatible, a license must also be a copyleft license -- meaning the license ensures that once a work is made available to the public, it cannot be taken away again. CC-BY makes no such requirement, thus it is not copyleft and is incompatible with the GPL."
This is just plain wrong. Several non-copyleft licenses are GPL-compatible, at least according to the Free Software Foundation . If the Creative Commons licenses are incompatible with the GPL, that's purely due to other reasons.
