Eh, a bit but it was varied within that. The Companions weren't really shitty. They were pretty thriving, it was partially you who came in and fucked thngs. And the College didn't have a hidden traitor as much as a neon flashing "Thalmor Spy, no literally, he even outright says it". In the Brotherhood, the traitor only betrays you (notably, only you, no one else (well, maybe Cicero, kinda sorta)) because she sees you as undermining her authority by your very existence. The only one that plays it straight is the Thieve's Guild.
