I'm not sure I understand your point.  The fact that there is disagreement among
vertebrate systematists on the exact pattern of relationships among the great apes
is not relevant to criticisms of the tenets of modern evolutionary biology.
Phylogenies can only be estimated by methods of data description and analysis that
we assume to be appropriate for constructing hypotheses.  If we threw out our
theoretical models every time independent researchers disagreed on particular
instances, then we would have no theories.

Again, am I missing something here?
