Well, possibly you were asking a different question to me. ;)
The question I'm interested in is:
"What is the safe thing for Quagga to do, that ensures we meet all our
I think the answer to this wrt babeld is pretty clear-cut, and you'll get
the same answer from most lawyers. Least, I've gotten what seems to be the
same answer 2/2 times.
I find it hard to understand why the discussion doesn't end there.
You could also ask:
"We want to distribute this code without GPL notices, is that OK?"
And here, yes, you could get different answers. Note that if one gets "No,
it's not OK" from one, that then going lawyer-shopping for the desired
answer may be a warning sign. ;)

Well, I trust the solicitor I got my advice from. I instructed them to
advise me in the interests of Quagga. I tried to frame the query as
neutrally as possible and state both sides (though, of course I am biased)

I don't see the challenge.
The Quagga maintainers got advice from SFLC in 2012 and discussed it quite
a bit. I don't have any reason to doubt that advice or to think we
interpreted it incorrectly, given other legal advice I've had.
We followed a reasonable process. We tried to do what was best and right
That one person who "doesn't care" about licensing is annoyed by that is
unfortunate, and I'm sorry about that. Again, I'm sure we'd accommodate
them as much as possible, within the constraints we have from the legal
advice that we have before us.
