We have clear examples of authoritarian states successfully suppressing specific topics. It's not so much about killing it as creating a line where consequences start happening. China is one example, where being too vocal about certain topics online can land you in a police station interview. I don't think we should be overly confident that similar things can't happen in the US or EU. And indeed, in the US we're seeing the administration successfully pressure changes at educational institutions for example. We're already uncomfortably far down this road imo.
