Is he still banging on about being "locked out" of twitter? I think he feels outshone by Medhurst and the others getting actually repressed and wants to feel like one of the boys.

I think you are too hard on him. In essence he is pointing out that there is serious repression of alternative povs. Do remember he has been subjected to this treatment way before Medhurst has been on the 'scene'. Remember the Venezuelan imbroglio a few years back? It may appear to be 'personal sour grapes' on the surface, not so imo. Cheers.
