Elisp licensing

[Christopher Howard]

Hi, if there is a long thread on this question already, please send me the link 
to that.

I was wondering if somebody could clarify, from a legal perspective, and from 
the perspective of the Gnu project, what is acceptable licensing for Elisp 
code? In my personal observations, finding Elisp in the wild, it seems like 
most people are labeling their Elisp as GPLv3+, not counting the code that 
doesn't have any license attached at all. But recently I came across an Elisp 
library marked LGPLv3+, and also another project that was under an ISC license.

My understand was that nearly all Elisp programs heavily utilize the Gnu Emacs 
API and libraries, and so they should be also licensed under GPLv3+. Maybe with 
exceptions for programs written for Guile Elisp or one of the non-Gnu Emacs 
clones that are being developed, like Gypsum or Rune. Actually, I believe Rune 
is marked GPL-3.0 and Gypsum is AGPL-3.0, though I haven't looked closely at 
their licensing comments.
