<i>But what is better? Even outside of it?</i><p>If you don&#x27;t know the answer to that question, then you are in no position to draw sweeping false dichotomies and grand proclamations as you did above. I have no interest in being your history teacher. I&#x27;ve posted plenty of papers on here, as has nickpsecurity here in the comments, and the link in my parent post provides a decent academic summary by one of the greats in the field.<p>(I&#x27;m not even sure if illumos can be described as &quot;widespread&quot; in any fair sense. In any event, being better than some relative competitors doesn&#x27;t give one the <i>carte blanche</i> to be a pseudohistorian and denialist.)
