That, plus times were different back then. We had to take what we could get. Unless you went to the library on a regular basis, or were otherwise "in the know", there was really no easy way to get any kind of information on Japan, much less anime and what it's all about. Now, in the age of the internet, where information is available with just the click of a (mouse) button (and forgive me if I sound like a bad technology commercial here), it's reasonable to expect shows like Macross to be seen as they were originally intended to be with the story as originally written.
All that said, you really can't blame those who (both back then and now) criticize him for what he did. Like I said before, he both a positive impact on anime, as well as a negative one. Still, it is sad to see him (or anyone else) go.
