As if that that mission statement on the wiki is not open to revision?
People may disagree with it, from within the project and try to change
policies. We can see a parallel to political constitutions which tend to
accumulate amendments. It is human nature to continue to rewrite and
reinterpret values. Therefore, OSM is not essentially the mission
statement or a "data project". What it is changes in time, as well as
being different to different people. A more useful way of
conceptualizing OSM, is to identify what we want to achieve and what
steps we can take to achieve it. (My non-mapping hobby is philosophy. I
am borrowing here from Karl Popper.)

Well obviously there are other licenses that are not compatible with
CC-BY-SA, but my point holds, at least for NC licenses: they are also
too restrictive and that is as much a problem with that incompatible
license as with CC-BY-SA. It is perhaps ironic that most or all SA type
licenses don't inter-operate, which I guess shows the limitation of

I tend to agree with your conclusion here, but my argument is driven as
much by avoiding the legal complexity of (b), as creativity. I am
actually pro-PD at this moment, despite my argument that ODbL is
diverging from the intent of CC-BY-SA.

I assume you mean it is "stronger" as in "enforceable"? Perhaps I am
missing another area of strengthening. The intent of CC-BY-SA is all
derived works are also SA. Otherwise, it seems ODbL is weaker - produced
works are not share alike?
I agree with thread comments that it is the community that makes OSM
work, not the license (although it is a small factor in attracting
them). And SA confuses various potential users, like the flight
simulators, from using our data (arguably ODbL is watered down SA to
make this less of a "problem").
I guess the big question is do we want to prioritize innovation of
mapping or do we want to create maps that most people will use? Only to
some extent can we do both. The decisions on licensing is driven by the
answer to that question, IMHO.
