Regardless, we should respect their claim. I agree with the basic idea:
it was the result of a creative process, and they choose to keep that as
proprietary IP. Therefore mpl will not include a clone of this color
map. If a user decides to make and use a clone, that's their business,
not ours. We shouldn't encourage it.

Perhaps they could claim copyright infringement; but from the mpl
perspective, I don't think it matters. The question will only arise in
practice if a user makes a plot with a clone of parula, and Mathworks
chooses to turn it into a legal issue. I think it is unlikely this will
happen; but if and when it does, I don't think mpl will be involved. We
will not be supplying the colormap or in any way encouraging or
condoning its use in mpl, unless and until Mathworks releases it.
