I would be fine with that, but I still do not see the point. IANAL but
as far as I know, using dlopen/dlsym to call a function in another
library does not create a new program, there is no notion of derived
work of any kind, this has nothing to do with either the GPL or the
license of the library.

If this is a purely ideological issue, and it feels to me like it is, then
why is it fine for Emacs to have functions to call external programs and
read their output? What if these programs are proprietary?
