I would like that. I really want to make this work, but I do not want
to be taking arbitrary demands to scrub expression of opinion.
Some specific questions for them, which we could discuss directly or
which you could convey to them first if you like:
1. If the problem is file boundaries ("if the license file
contains..."), would this be any different if there were no "license
file", only one big README, and both texts (statement of opinion, and
copyright/license statements) were in the same file but separated by
section headers? I'm not really proposing doing that (although it's
one potential silly solution) but rather trying to draw out the
absurdity (as I see it) of deeming text that specificially says it's
NOT license text as if it were just because it's in the same file.
2. Taking that in the other direction, what good does it do burying a
record of our beliefs about the matter? It's not like we can erase
past statements. Taking the text out of the COPYRIGHT file increases
its distance in space and time from the license text, but it doesn't
change the fact that they were published together in the past. If
anything I think it's a disservice to parties who are (IMO wrongly)
concerned about the implications of such beliefs not to disclose them.
Having clarified text in the same place puts emphasis on the intent
that they not conflict and that we actually put effort into clarifying
where there was a perceived conflict.
3. I understand lawyers want to minimize risk. I don't understand how
a statement of opinion that, if it were deemed relevant and deemed
true by a court, would imply that we (actually nobody) has standing to
sue creates any risk. To use the UB analogy, when someone reports a
claim of UB, we actually want to see a code path that leads to UB
happening (without UB already having occurred by violating an
interface requirement), not just a claim like "if variables X and Y
have values A and B, UB results". Of course if there's a proposed
change that's simpler and doesn't require tracking down if UB actually
occurs, we'd just consider that outright, but when the current code
has advantages, there should be a real motivation to change it. If
we're going to treat the matter here as a "bug report" against the
COPYRIGHT file, I want to have an understanding of the alleged bug.
4. I'd also like to understand what the claim-copyright vs
not-claim-copyright distinction they're making is. As an analogy,
suppose I've written a math textbook containing "1+1=2" in it. The
statement "1+1=2" is most certainly not subject to copyright, and my
saying that (within the text or outside it) does not draw into
question the copyright status of the textbook. I really don't see any
difference between this example and what we're saying here with
regards to these files. We are claiming copyright (and asserting a
right to do so) for the work as a whole. The statement of opinion is
on the matter of these files taken by themselves. If the problem is
just that this isn't clear, maybe there's a trivial way to clarify
that and make everybody happy.
I know this has been a tedious process of back-and-forth and is using
lots more time (on both of our sides) than we'd probably like. But I
do want to see something good come out of it. Let's arrange a chat
with the lawyers (this probably can/should be done off-list) and see
what comes out of it.
