They are hashing out the details on the email thread [1]. I don't know how correct it is but this post [2] in particular tries to give some numbers:

You mention an estimate of $400k as annual turnover for the OPW, which (according to the most-recently available annual report that I can find, the 2012 one at https://www.gnome.org/foundation/reports/) is very close to the turnover of the Foundation as a whole ($418k income and $409k expenditure). Those 2012 numbers include $106k of Women's Outreach expenses, so the turnover of non-OPW Foundation tasks seemed to be somewhere in the region of $300k.

So apparently it caused turnover by being a huge source of growth.
