AirNZ had no input in the article and therefor had no control over the messsage put out.
I'm not sure I agree with the writer that money was the major reason QF did not fly, I have called my reasons previously. Fixed costs still acrue while on the ground, and I would have thought it would be cheaper to burn a bit more gas to get round the ash than the associated costs of not flying at all.
Perhaps we will all become a bit wiser as to QF's real reasons for not flying on Aug 24.
