Indeed.
We have no trouble at all running programs with much worse licenses than
the GPLv3 (ie commercial programs). There is no problem with user space
being v3.

...and here's a thing that most people forget: good code simply doesn't
care about ideology, and ideology often does the wrong technical decisions
because it's not about practical issues.
The watch-word in Linux development has been "pragmatism". That's probably
part of what drives the FSF wild about Linux in the first place. I care
about _practical_ issues, not about wild goose chases.
If I weren't into computers, I'd be in science. And the rules in science
are the same: you simply can't do good science if you start with an
agenda. If you say that you'll never touch high-energy physics because
you find the atom bomb to be morally reprehensible, that's your right, but
you have to also realize that then you can never actually understand the
world, and do everything you may need to do.
I've often compared Open Source development vs proprietary development to
science vs witchcraft (or alchemy).
In many ways, the GPLv3 is about "religion". They limit the technology
because they are afraid of it. It's not that different from a religious
standpoint that some research is "bad" - because it undermines the
religious beliefs of the people. You'll find extremists in the US saying
that things like evolution is an affront to very basic human morals, the
exact same way that rms talks about DRM being "evil".
I want to be a "scientist". I want people to be able to repeat the
experiments, logic, and measurements (that's very much what science is
about - you don't just trust people saying that the world works some way),
but being a scientist doesn't mean that you should let other scientists
into your own laboratory or into your own home. That would be just crazy
talk.
So as a "scientist", I describe in sufficient detail my theory and the
results, so that anybody else in the world can replicate them. But they
can replicate them in their _own_ laboratories, thank you very much.
That's what open source is all about. It's about _scientific_ ideals.
It's not on a moral crusade, and it never has been.
The point behind all this: even if the Hurd didn't depend on Linux code
(and as far as I know, it does, but since I think they have their design
heads firmly up their *sses anyway with that whole microkernel thing, I've
never felt it was worth my time even looking at their code), I don't
believe a religiously motivated development community can ever generate as
good code except by pure chance.
