If everyone hates censorship so much, why do those “censorship-free” alternative social media sites always fail?

Because you’re confusing two different things.

Child pornographers.

Who is the #2 user of completely free digital communications networks that let you say absolutely anything? Who else wants that?

How common is it for siblings to fight over their parents' inheritance money? What is the best way to handle this type of situation?

Why is Reagan seen as the best president in the USA when he literally destroyed the American economy with trickle down system and was strongly against worker unions?

I hate censorship. That is, I think the government has no place controlling what people say, read, express, or create, except insofar as is necessary to prevent things like terroristic threats, dissemination of classified information, fraud, false advertising, and so on.
