Since I "asked" the referenced question, let my explain my reasons.
Most questions about licensing that have a relation to the GNU licenses are already answered in the extensive Frequently Asked Questions about the GNU Licenses. But almost none of the answers to such questions refer to this FAQ or just add a comment to the question saying that it is a FAQ and not worth repetition here. What people do is to answer such FAQs, often not adding anything that is not covered in the external FAQs (that happens for FAQs already answered by the FSF, OSI, and CC).
Why do we even answer such FAQs?
I do not add questions as seed questions but to highlight the fact that so fare this whole SE site contains very little original content. It mainly is a collection of information found somewhere else.
Why do we duplicate information for which there already are established sources?
