Nobody, AFAIK ... but we should be careful.

I think they understand the spirit of cooperation; I much doubt they
understand the "kiai" (unyielding martial spirit) of Copyleft.
Copyleft is a double-edged sword; it can inhibit, as well as promote,
cooperation.  For example, the incompatibility of the GPL and the FDL
is quite annoying in a language that supports docstrings.

This is not a problem.  (Unless, of course, he applies the same logic
to the FDL, thereby unwittingly creating problems for would-be forks.)

However, if the software in question is derived from Emacs, and he
doesn't understand the GPL, he's very likely to engage in the kind of
"cherrypicking" David Kastrup warned against encouraging.  Eg, failing
to distribute source or a "written offer to supply source" with
binaries to people "who don't want it".

I've done that myself (in 1991, when I really had no clue about GPL; I
believe that nobody was denied the chance to exercise GPL rights that
he would have wanted to, but technically it was a violation).  You
see, me, ca. 1991, is who I was aiming the first draft for.
