Professors at public schools with tenure have an intellectual duty to themselves, their students, the school and the taxpayer to defy forces that try to silence them.
This defiance looks sad unfortunately, no offense meant to the author here as I respect his attitude. He mentions blogging being in his plans for the future, but even here in HN this post already looks like it's shadow banned and the blogpost has one like. Not all defiance is made equal, this author has a huge uphill battle and I wish him the best.
