The difference you seem to be overlooking is that basically no one wants to receive abuse, spam or malware, whereas (depending on who is doing the censoring and who is being censored) maybe 30% to 50% of users want to receive the messages that the censor decides is "hate speech".

I think what you're actually saying is "I advocate for centralized platforms combating hate speech provided their definition of that term happens to agree closely with my own".
