Usually when people say an old episode of a TV show has been "banned" they mean it has been removed from a couple of streaming services. They're just being extremely dramatic and hysterical.
"idk, maybe now you'd agree it's bad how corporations can make things disappear on a whim and there should be some regulation to that?"
"Stfu that's communism"
I have a theory that most of the TV shows you enjoyed say, 20 years ago, if you were to watch them now, you wouldn’t find them anywhere near as good as you remember.
Chances are people watch a couple of episodes, this reality kicks in and viewers dwindle. Makes sense not to continue streaming.
