No, the sisters were criticized because the slam finals were crap.
Consider Graf for example. She dominated for 10 years but no-one complained because she presented us a lot of all-time classic slam finals (eg. FO 87, Wim 88, FO 89, Wim 89, Wim 91, FO 92, Wim 92, AO 93, FO 93, Wim 93, USO 94, Wim 95, USO 95, FO 96, USO 96, FO 99).
OK, in the U.S. there was some criticism but that was due to Graf not being American ...
