"www.loyalty.org itself is the server for the web site of Californians for Academic Freedom, the group I founded to oppose the California loyalty oath, which is still a non-negotiable requirement for anyone who wants to work for the State of California -- including student employees of the University of California. "
That's the most controversial thing about the page. In my view it's not a big deal to have that stance but some people don't like others who rock the boat when it comes to the status quo.
My activism on this issue for the past decade and a half has basically consisted of corresponding for a few minutes each year with some new person who objects to signing the loyalty oath. I doubt that the site blocking has anything to do with this.
