How do you know she can't make pure pop? She created ARTPOP THREE ago and it was released ONE year ago. Back in the day when she was recording ARTPOP Dance Pop was still popular. What did you want her to do? Scrap ARTPOP and record a whole album because EDM is not as popular in 2013 as it was 1-2 years before?
She's already working on new projects and no one is satisfied. "No Jazz is boring", "I will revoke my stan card if she did ballads or acoustics", "Classic rock is not my taste", "Go back to RedOne", "No, don't go back to ReDone". She will never be able to satisfy everyone.
