Regardless of that, is your solution to a decades old problem that pre dated the internet is to ban online forums that don’t tow approved narratives?
I think you will be incredibly disappointed in the results of your solution.
I do not like companies being the arbiters of good, but in this case (as far as CF is concerned [1]) I believe they did no wrong.
They clearly state that they should not be in the business of policing legal content they host, but also work hard to make sure they are not hosting illegal content. This way is better than a twitter-like approach where you only pay attention to high profile situations.
(In many senses twitter is doing a good job, but in other senses they (and their employees) have a strong political bias that bubbles up to how they enforce policies)
