Not really. Certain strings are considered acceptable -- keeping a
changelog, for example, or changing the name. The question is which
strings aren't acceptable. That's why we have tests like the Desert
Island test & Dissident test -- they help us to draw a line
distinguishing acceptable restrictions from unacceptable ones. But in
this case the question isn't whether the restriction is significant,
it's what's being restricted.

Yes, but this isn't just copyright -- hence the click-wrap. We could,
of course, conclude that without going beyond copyright use restrictions
are impossible, thus not worth mentioning in the DFSG. But then what
about confused folks (or just folks in other jurisdictions?) who claim
use restrictions can come out of copyright? If we accept their claim
(as our policy generally suggests) it's still non-free, even if it
doesn't have a click-wrap.

Absolutely. That's why I don't hesitate to say it's non-free, despite
not seeing how to ground that claim. But I do think that not finding a
grounding is a very important thing to note. At the least we should be
explicit about that in the summary, and at best we should try to find a
way to fix the DFSG so this particular issue doesn't show up again.
Frankly, that has the advantage of giving d-l's claims more legitimacy,
because we're following an appropriate procedure for getting this sort
of problem fixed, rather than appearing to be zealots trying to take

But the goal isn't to handle every future kind of non-freeness. Just
this one. In my opinion, when we have a situation where we are
convinced that a clause is non-free despite not being able to ground
that claim in the DFSG we should:
- Provisionally state that we're calling the license non-free
- Come up with language that captures our intuitions on why the clause
- Start working to get that language added to the DFSG
Assuming everyone agrees that this clause is non-free, and that no one
is able to point out why in terms of the DFSG, we need to decide how
best to capture this issue (and hopefully this class of issues).
>From what you say above, you see this as fundamentally about use
restrictions. On thinking it over, I think you're right. I'm hesitant
to try to describe it in terms of forced distribution when the GPL
already forces distribution of source code.
For example, one possibility would be to substitute the following for
DFSG #6 (since this is just a more general case):
6. No Discrimination Against Types of Use
The license must not restrict anyone from using the work for any
purpose. For example, it may not restrict the work from being used in a
business, from being used for genetic research, or from being used to
provide web services.
I can't think of a more conservative change that could be made that
would capture this particular problem.
