Re: GPL vs non-GPL device drivers

So far I have heard nothing but, "if you don't contribute, screw you."
All this is fine. Just say so. Make it black and white. Make it
perfectly clear what is and isn't legal. If we can't load proprietary
modules, then so be it. It will help everybody if this is out in the
clear, instead of resorting to stupid half measures like
EXPORT_SYMBOL_GPL.

But so what? How will that hurt *Linux*? If the Embedded developers
don't contribute changes back, it doesn't hurt us any if they go away
and start paying $$$ to VxWorks instead of using Linux for free.

Contrawise, if Embedded developers do contribute their device driver
changes back to the kernel, they will be fine. Note that we don't
even force them to do the work to make it be mainline acceptable; they
just have to make the sources available. It could be crap code, but
it will fulfill the requirements of the the GPL. Others in the
community can make the decision about whether they want to clean up
the code and get it mainlined, or it ignore it if it truly is a
one-off driver. All you have to do is make the driver available.

And if you don't, why do you think that it is at all a credible
threat, or that we should shed even one tear, if you go away and use
some other OS for your embedded product? It's not like in the case of
VxWorks where you get to say, "Do X or we take away a million dollars
worth of business." And on the flip side, what I think you will find
is that if you do contribute to the community and be a good community
member, others will cut you some slack when the time comes because
you've built up the good karma. But that requires that you be a good
community member. If in contrast you find that it's cheaper to pay
$$$ to some embedded OS company, please feel free to do this. No one
is forcing you to move from Linux 2.4 to Linux 2.6, or even to stay
with Linux.
