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

Because you’re confusing two different things.

Why do “censorship-free” social media networks always fail? Well, let’s see. Sit down and think. Think really, really hard.

We don’t have to guess. We know.

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

You have the right to say what you want. You do not have the right to use other people’s stuff for free.

If i let you use my computer network for free, I have the right to tell you you can’t do certain things with it, and I have the right to kick you off. Why? Because it’s my property, not yours.

That has nothing to do with social media.

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.

Nazis.

Why does it seem that Quora's "moderators" base their moderations on personal beliefs and views by deleting answers that are only violating their personal feelings?

Child pornographers.

If I let you borrow my bike for free, I have the right to tell you you can’t do certain things with it, and I have the right to take it back. Why? Because it’s my property, not yours.

“Censorship-free” social media sites quickly become Nazi bars where people exchange child porn. Normal human beings don’t hang out in Nazi bars with pedophiles.

Can you summarize season 1 of "The Acolyte"?

The #1 problem people who make and consume child pornography have is connecting the producers with the buyers. Any “censorship-free” network quickly gets overrun with child porn. Classic example: 8kun.

The #3 user? Terrorists. 8kun was used to plan 3 different school shootings in a 6-month period.

Now, say you’re an ordinary person. You don’t like child porn. You’re not a Nazi. You don’t want to shoot up a school or blow up the White House.

A protestant (one that adheres to sola scriptura) disagrees with a catholic. How do they propose resolving the dispute?

Who is the #1 user of completely free digital communications networks that let you say absolutely anything? Who most wants that?

Are you going to stay on a social media site that’s all photos of babies being raped, Nazis posting graphic descriptions of finishing what Hitler started, and plans for school shootings?

So.
