She was caught plagiarizing work on multiple occasions.

She and her ilk set a double standard up on campus regarding speech, favoring certain groups over others. Anyone who is objective sees the double standard regarding speech on campus (what speech is considered "violence", heckler's veto for conservative speakers without any punishments), and she embarrassed her university by allowing and enabling this rot. This was all exposed and she subsequently resigned. You're probably right in that she was nudged to that position by people both inside and outside the university, but she certainly could have demanded a more formal process that may or may not have let her keep a high six-figure position. You don't like the politics behind one of the people who helped expose her plagiarism, ok. But that kind of stuff happens all the time, in the numerous examples above, not to mention politics invading our legal system as people search out grievances to sue over in order to make a political point (gay wedding cakes etc.).

Harvard is the most prestigious and well-known university in the country, I have no doubt there are plenty of qualified candidates out there who haven't plagiarized to the level she did and who would likely be more proactive in cracking down on obvious double standards for speech on campus.
