While the title of Marc's email might be construed as flame bait, it is
disappointing to see that the generally very valid points he has made
(as both a BSD _and_ _GPL_ developer) are being ignored. To make it
simple try answering these two questions:
----
Question #1: Is it _ethical_ (legality aside) to take someone else's
actively maintained work (for example an OpenBSD driver) and make
changes which can not be shared/used by the original developer/maintainer?
Answer #1: Considering that the whole reason I personally choose the GPL
for some projects is to prevent this sort of one way street behavior
_away_ from the original OSS developers/contributors _my_ answer must
be; No it is not ethical.
----
Question #2: Is it _technically beneficial_ to branch an OSS work (for
example an OpenBSD driver) in such a way as to diminish the ability to
share contributions between projects?
Answer #2: It would be fascinating (and sad) to see an attempt at
justifying a yes response to this question.
Please don't let the rude language or defensiveness bought out by this
particular incident distract from doing the right thing. Just because
you legally can (or might be able to) do something doesn't make it right.

P.S. As a secondary concern; it could be legally dubious with some
governments to relicense an existing file from the OpenBSD license
(given that the copyright license must remain intact) -- though patches
could themselves _technically_ be GPL. Creating _new_ GPL files which
work _with_ the existing BSD licensed has no such ambiguity, but please
see questions #1 and #2 above -- is it the _right_ thing to do?

I beg to differ. If you want to put things out there for others to use
but want to avoid having the situation as you describe it, simply
license the work as such (which would be neither BSD nor GPL)-
requiring any changes to come back to the original maintainer.
*Snort*. I seem to recall Unix commercial distributions that made
claims that bug fixes that you made belonged to them.

This happens all the time. It's called a fork.
Forks happen for good reasons, bad reasons, dumb reasons, and smart reasons.
Sometimes the useful changes can be shared back, and that's a good thing
[for that situation].
Sometimes changes cannnot be shared back, and that's also a good thing
[for that situation].

Can only be answered on a case-by-case basis.
The reality OF THE CODE is such that *BSD and Linux share good SOLUTIONS
quite often. That's a benefit of open source. And that's a good thing.

... But is it _ethical_ (as opposed to legal) to violate the expressed
intent of the original author ...
IP laws (including copyright) are generally used as an imperfect (and
internationally inconsistent) mechanism to protect intent, but inexact
application of those laws affects enforcement as law ... however,
respect for intent remains the ethical standard by which I (for one)
would prefer to govern my life.

The author expresses his intent primarily by choice of license text, and
it's very important to all of us that we follow the rules set forth by
the author in that license text.

I have released software on more on one occasion where I have given a
very liberal license (like MIT), and then put a "however, if you like
this, X would be appreciated." I wouldn't consider it unethical if
someone didn't obey the optional request (it's optional for a reason),
however, it does mean that I do genuinely appreciate someone doing X.
So there is a difference between what is legal and ethical, and what is
the nice/friendly thing to do.
