Ehhh, that's a bit of simplistic take on the Unidan story, a lot of scientists were happy to see him go. He spent a lot of time marketing himself so that he became THE biology guy on reddit. The problem is that biology is a pretty broad field, so a lot of his answers were basically wikipedia recaps paraphrased into his "Unidan" voice - answers by people actually knowledgable in the matter at hand would get drowned out (and downvoted by Unidan's alternate accounts, of course).
