Here we go again.
Different people have different opinions of point counters. DougZ has done a pretty good job of altering isotropic to allow for people on both sides of the argument to play the way they like. I, personally, do not like playing with the point counter, so I prohibit it when I automatch, and do not enable it when I specify opponents. I completely understand the arguments from the other side, and so I accept that some people will use point counters. I no longer have to play with them so that is fine. Now all we need is for the use of third-party point counters to die out and isotropic will be perfect.
I would suggest that you had every right to check the point counter in the games you mention, provided we are talking about the isotropic-implemented counter, as your opponents had willingly entered into a game that used the point counter. Isotropic's interface lets you know this beforehand, so there is no argument really.
