Not sure where to post this… happy to move it if there is a better spot…
I’ve yet to a see any meta license—terms for reuse of a license text—that restricts who can use it, or how. Mitchell, K. 2021
How about this?
Copyright © 2007 Free Software Foundation, Inc. https://fsf.org/
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
I wrote them.
Paraphrasing, they said it’s because they are worried that someone could completely change the meaning of a clause, maybe by adding a ‘not’ here and still call it the “GNU GENERAL PUBLIC LICENSE” and cause some terrifying problems.
I said that would probably be snagged by lawyers keen to litigate for something like ‘passing off’ and/or maybe ‘unfair’/‘misleading’ etc. and so illegal/unenforceable as far as it is possible to go.
Anyway… they also, unambiguously say:
You can legally use the GPL terms (possibly modified) in another license provided that you […] make it clearly different in wording and not mention GNU (though the actual procedure you describe may be similar).
Combined, I would say this is all adds up to a fairly ‘meta’ kind of effort… and the intention and effect seems to me to clearly want to restrict how the license can be used?
