I just don't think that's true. Many people have opinions that will lead them to being attacked and cancelled, etc. There are groups of people ready to isolate and pounce on whoever they can so as to compel others to shut-up.

I get what you're saying but I don't agree that government has a place in regulating speech. People are free to join or leave platforms as they see fit.
