The casting has absolutely nothing to do with pleasing/pandering to any one group. Sony hired Paul Feig to do this movie, since Akroyd and Murray were never going to come to terms on an actual third movie. And let's look at what Feig's biggest successes have been. Bridesmaids and Spy. So is there really any shock that he would make a female lead comedy?
I'm not sure anyone is surprised. Mostly just disinterested.
