How disturbing. I think we thought it had been.

Actually, I think most of clause 4b is fine; it's only one little bit of it
which is troublesome. I will now analyze it carefully:

So far free.

I think this is a reasonable and free requirement. It's trivial and easy,
and amounts to nothing more than proper attribution.
>the title of the Work if supplied;
This is a stronger requirement, but I also think this is reasonable and a
free requirement. This *does* correspond vaguely to requiring appropriate
references to prior work (as is done in scientific papers), unlike some
other things we've discusses. Also, it's standard practice in the free

Likewise this is a reasonable and free requirement.

Great! In other words, for Debian, we put it in the copyright file along
with all the other credits. Or we put it in a CREDITS file or a
CONTRIBUTORS file or a NOTICES file. Or next to the copyright notices in
the files. Or whatever. Except then there's this next clause....

*This* is the problem clause. It's unclear to most of us exactly what "any
other comparable authorship credit" means. If it means "the credit given
to any other author who wrote approximately the same amount of the
material" -- then it might possibly be a free requirement, or it might not
(I'm not sure, since I haven't thought about it); but it's ceratinly an
ugly requirement. If it means "the credit given to any other author of the
same work", it certainly isn't. If it means something else, I have no
With this ambiguity, the "at least as prominent" requirement is then a
potential interpretation nightmare. Suppose, for a silly and extreme
example, you wanted to use a huge hunk of material under this license in a
version of ReiserFS, so that the code under this license needed a
"comparable authorship credit" to Reiser's. Would that mean that the
credit would have to appear in the FS name, so as to be in the same
location and at least as prominent as Reiser's credit? Yeech.
"Prominent" credit requirements are the specific type of credit requirements
we've been objecting to. They cause endless trouble in a way that ordinary
credit requirements do not.
This might be fixable with a clarification, or a lawyer's opinion on what
exactly it *means*, rather than a license change.

Right. This is the deal-breaker clause, which absolutely must be fixed to
create a free license.

This isn't supposed to be an actual part of the license, according to the
source code for the web page; this should be fixed so that this is clear
when *viewing* the web page (it is *not* clear now). That doesn't require
changing the license. It does require someone at Creative Commons noticing
and dealing with the issue. :-P

I hope there is some. My previous comments must have been going to the
wrong address or something. You can forward this if you like.
I speak only for myself, of course, etc.
There are none so blind as those who will not see.
