Yep. But isn't much GPL code that gets rewritten this licensed under the
GPL (as opposed to say BSD) precisely BECAUSE the authors didn't want them
to be compatible with BSD licenses and thus able to be incorporated into
works without reciprocal licenses?

If this isn't the case, can we assume the FSF (to whom much GPL stuff has
been assigned) will be dual licensing it all under a BSD license? I think

The point here is the license is the AUTHOR's choice. Good licenses will
thrive the same as good code thrives (viz. ESR's bazaar analogy), as if I,
HP, Joe Blow, whoever, doesn't like the license, doesn't like the cost of
evaluating the license, can't read the license because it's written in
English/French/Klingon, then they have the choice of not using it, and
using something else instead. That's "the market" / "natural selection".
Same as closed-source, except of course they are guaranteed a full refund
on FOSS :-)
