If you start it you have to mean it. It can only stop when the guilty parties are purged, not when they throw a bone and sign a stop gap star. You don't protest to get them to do something, you protest to get them out. It is hard to shift vermin of this type though, they have a powerful weapon. They can punish you by accelerating the destruction of the things you loved all your life. And they ave the media, they can blame you for their crimes and get away with it. So real protest with an end goal is potentially a bloody affair. I have little faith in the denizens of the library to pull off anything significant, except maybe Kroenke's dick when he chucks a loss leader at them.
