Hmm, so I should not only have consulted it, but agreed and disagreed
with the correct bits of it?

The article did not even mention Turing! It pointed out the differences
and similarities of the capabilities of the 'traditional' computer and
the quantum computer in quite a straightforward manner. It seems to me
that you noticed that Turing-Church doesn't do a very good job of
modelling the differences they described, and thus rejected the article
because it challenged your preconceptions about the issue.
