It's hard to control people if actual opposition exists you know, but they still need to give the illusion that there's still an opposition. After all, you can't really profit if everyone agrees with one another and It helps putting a leash onto your opponents, so they created something called controlled opposition. Just like it implies, they aren't going to do anything but talk. They "hate" what's going on in this world, but they won't do anything about it. They're all bark but no bite for a reason. You can tell if someone doesn't have any strings attached to them or have theirs cut when they're getting ridiculed by the press from both sides or/and they're heavily censored.
