In ShB, we see someone deemed the "Amaurotine Firebrand" protesting vehemently against many of the Convocation's policies, and he is likewise allowed to voice his complaints even to groups who did not agree with his position. Likewise, while Amaurot was a capital, we know for a fact that both travel and long-range communication were common for them, based on the teleportation devices on Elpis, as well as the fact that the Amarotine shades mention hearing word from outer provinces. So it didn't seem to matter very much if people were in the capital or not when it came to making their voices heard.
Besides that, all of which you describe is taken up to an even greater extreme with Venat. Outside of a very exclusive circle which largely agreed with her, no one even knew about Venat's plans or goals (and even then, she still seems to have kept most of the truth from them, if the Watcher is any indication). Just like real life democracies and republics, Amaurot and the Convocation were in no way perfect, but still leagues better than any dictatorship or shadow cabal in terms of accountability. The problem with Venat is that she pretty much WAS a dictator in charge of a shadow cabal, who made genocidal decisions on her own volition and with ZERO chance for debate or oversight. Any criticisms you can lobby towards the Convocation's style of government are multiplied upon Venat.
