I think you're forgetting the mass censorship, which you so cutely describe as "ask it to go elsewhere".
If the original Reddit, facebook, or most other OG forums were introduced today, that "one group" would do everything in their powers to take it offline. The everyday members of that group also refuse to use that service until it conforms to their censorship needs.
Until you win hearts and minds, nobody's going to want to hear what you have to say. Strafing a community with truth bombs will not endear them to you, even if you're right.
How so? A sitting United States president was mass banned a few days apart by Facebook, Instagram, Twitter, Reddit, Apple, etc. Hell, even Shopify, a Canadian company joined in the fun.
