So we should forget the prequels where a Sith operates in private to gain power? Same Sith who resurrected himself? Should we forget the last thousand years where the Sith operated so secretly that they were thought by the Jedi to be extinct? Or the comics where they explore wanting so desperately to kill Jedi, but needing to maintain their secrecy more? How about the originals where Palpatine gained power and never revealed he was a Sith to the masses? The Sith ARE the shadows. I agree that the story wasn’t fleshed out well enough in the sequels. They have their flaws, and this may be one of the biggest, but the idea that the Sith would operate publicly and transparently is laughable.
