If you are a famous/semi-famous public intellectual over 50 and you are not aggressively getting cancelled by leftists, then you have been infected by social desirability bias and your ideas will not age well.

Do you care about your intellectual legacy? Then be brave.

"I am famous but the leftist cancel mobs are leaving me alone" is a very, very strong signal that you are self-censoring (perhaps even without realizing it) or you have started drinking their cool aid.

Think about whether you are happy with the implications of that.

Obviously don't just start edgeposting; but the people I am thinking of with this likely won't do that.

Also, if you don't have hundreds of thousand of dollars in savings and property, you might want to keep quiet on purpose in order to avoid being utterly ruined by the mob.

But many of the people who self-censor have enough in the bank that they are basically cancelproof.

They don't want to deal with social ostracism. Well, this is the time when you have to choose whether to be correct or popular. A lot of very talented, smart people are going to choose the latter and they will go down in infamy for it.
