I noticed the question How to license program output? which is a verbatim copy of an entry of the GNU GPL FAQ. Naturally, the current top answer also quotes said entry of the FAQ.
Should we get content for this website by simply mirroring content from official FAQs?
Are we even allowed to do this copyright-wise? The page the quote comes from is licensed under CC-BY-ND 4.0, while all stackexchange content is licensed under CC-BY-SA 3.0. AFAIK licenses are not compatible because SA allows changes while ND does not.
