i think the issue here is a kind of crossroads.
at the one hand open source people want to thinker with as much as possible of
but at the other hand, every nation that have at least some form of working
government wants some control over whats going on across the EM spectrum.
therefor one need a way to verify that a device complies with the regulations.
one way to do that is by signing the software so that only if it comes from a
known "good" source, its allowed to be used.
another, used by fic in the neo, is to embedd the stuff that generates the EM
waves inside a chip that cant be reprogramed.
as long as the linux kernel and all the other code used is under GPL2, there
will not be a problem with this. but if some of its under GPL3, they either
have to look for alternatives, or drop this function.
thats one potential problem with the FSF, it attacks the act of signing, no
matter why its being used. with tivo its used to enable the content producers
control of their products. but on a phone its just as much about being able
to use them at all. because a EM emitter is also a jammer, and can
potentially block all other uses of a frequency if its not behaving.
