I won't speak as the authority for ZC, but I will say that we have not
used an ODBC-based DA for any recent project (read: for several years).
Where we do use an RDBMS it is almost always MySQL/PostgreSQL. It is not
practical for us to maintain software which we do don't ourselves use
for production. 

Part of the implied contract of open-source software is that users of
that software are compelled to contribute to it when they perceive it
lacking (or they can find another solution of course). Sometimes the
original author of a piece of software no longer uses it. In that case,
others using that software can take on the task of maintaining it. The
fact that this is possible in the open source world accounts for an
appreciable part of its success.

Where it has come up with prospective ZC customers to connect to MS
databases from Zope, the use of mxODBC has been brought up immediately
and without hesitation. I strongly suspect we would choose to use it
ourselves over updating ZODBCDA. It simply makes no sense from a
business standpoint for us to do so when others already offer a working
solution for a fair price.

Please remember that just because software is released to you for free,
that does not mean that it has no cost to you. When using OSS, you must
be prepared to invest the time needed to integrate it. That may mean
getting your hands dirty and writing some code, or paying someone else
to do so.
