Another old paper along similar lines is

Clark, Curtis and Daniel J. Curran. 1986. Outgroup analysis, homoplasy,
and global parsimony: A response to Maddison, Donoghue, and Maddison.
Syst. Zool. 35:150-154.

which you can download at

As I remembered, we had some specific criticisms of some parts of
Meacham's paper, and agreements with others.
