Not every time. Those mentioned were mostly the exceptions.
Tons of people were on the show not as themselves.
Daniel Radcliffe wasn’t himself or Harry Potter on the show. He played a character that was a parody of Twilight. It had a somewhat decent enough joke and wasn’t just hey look at this famous person we got. Look how cool they are. Ooohhhhh ahhhhhhh
And those were the exceptions and not an every episode occurrence. Some of those also had good points to make like Lisa going vegan. Very much not how the modern cameos go.
Somewhere around the point of Lady Gaga driving into Springfield on a magical train it became celebrity ads.
