As many of you are well aware, John Hunter has been the sole
copyright holder on matplotlib from the beginning. I’m sorry it’s
taken nearly a year to do this (as can often happen in sad
situations like this), but I think we do need to address it going
forward.
I have a PR for this change in #2195.
Heavily influenced by the IPython licensing, I propose to move us to
a shared copyright model, where authors retain copyright on their
individual contributions, but the code base as a whole belongs to
the entire community of contributors. This does not actually change
the license from the BSD one that we have had all along, so should
have no impact on its usability in or with other projects. I feel
pretty strongly that this is the right direction, as it reflects
that matplotlib was and is a community project. (And just to be
clear, this is in no way an attempt to reduce John’s credit for the
amazing work that he began).
I hope this will be noncontroversial, but I'm always wary of
starting legal discussions on a mailing list.

Not that I have any right to speak for him, but I suspect/imagine that
he would have been totally on board with this plan, and I wouldn't be
surprised if the fact that it hadn't happened before wasn't simply an
oversight.
Very happy to see you take this step, I think it's the right approach.
Cheers,

Purely as a legal matter, I believe that what you mean is, you're
suggesting updating the documentation in the source files to more
accurately reflect the current model? Unless everyone's been signing
written documents transferring their copyright (which is the only
effective way to transfer copyright in the US and AFAIK most other
jurisdictions), then right now matplotlib's copyright is owned by the
community of contributors, and has been so long as there have been
contributors.

IANAL, but I assumed as much. The real problem I'm trying to resolve is that the explicitly specified copyright (whether it applies or not) is still John Hunter.
IPython changed from explicitly listing individuals in their copyright line to referring to the IPython community fairly recently, and obviously under different circumstances. Fernando -- was there a particular impetus for that or model you were following?
