I think you’ve also got to allow for a certain amount of incompetence: accidental blocking of the wrong site, blocking of sites for very poorly-thought-out reasons, and ass-covering evasion or stubbornness in the face of any questions about why some apparently pointless decision was made.
Not necessarily in this case of course, but it’s a phenomenon inseparable from the very idea of politically-mandated censorship. Or politically-mandated anything, really.
