Virtually everyone who complains about it. The complains are almost always about how sensitive people are today, how blazing saddles couldn't be made today or whatever non-sense they use to rage farm. Its almost always framed as a today problem.
When you look at historic examples of cancel culture its almost absurd at how tame their offenses were. Dixie Chicks are another example that come to mind where critical but not controversial statements are made and it ruined people's careers.
McCarthyism, the Red Scare, and the Hollywood Blacklist of the 1950s.
Untold Black American artists, authors, and creatives who fled to Europe: Nina Simone, James Baldwin, Josephine Baker, Paul Robeson, Augusta Savage, Romare Bearden, Jessie Fauset, and Richard Wright just off the top of my head.
The problem they have, of course, is not that cancel culture exists. It's that the center of force of "cancellation" went from the right to the left. The thing they used to great effect against queer people, anti-religious people, etc, is now being directed at them. It sucks being on the other side.
I personally think that things are too "hot" right now, but nobody should pretend this is a modern problem.
