First of all, saying that because I disagree with Dear Leader I must support the entirety of your enemy's beliefs is exactly the sort of argument that a Reddit SJW would make, so careful with the fedoralord libertarianism there, frienderino.
Second of all, acting like there is literally no space between Reddit and KiwiFarms is obviously false. If his vision of the future is correct and no site like KiwiFarms could exist post-230, then Null can run a site that is some percentage of his perfect website, or he can run nothing at all. Nothing could accelerate the collapse of free expression on the internet more than every site right of Reddit shutting itself down out of fear and not even trying to fight. Null knows lawyers, programmers, "influencers", etc. - there absolutely is some way that websites will be able to survive the future and he knows people who could help him do so. Worst-case scenario might be that the site has to go down for a while as Null figures out how to legally cover his ass and reopen with some restrictions.
You act like me saying that compromise is an option is worse than me advocating for the total destruction of the freedoms you are trying to protect. Null is not fighting for freedom by destroying the site - he's actively shifting the landscape towards the Reddits of the world.
Have fun talking to nobody, alone in your room, because the absolute purity of your beliefs couldn't be reconciled with a hostile social environment for a little while. That sounds so much better than being able to express yourself with a somewhat limited vocabulary on a website that otherwise still provided diversity of thought. And I am sure Null will be so much happier in 10 years as he works in his cubicle making someone else rich and knowing that there are gossip sites out there who ate KiwiFarms' corpse and built a fortune out of a market he abandoned.
Again, he should fight for his sake, not for your sake or my sake or the sake of freeze peach - but him choosing not to fight hurts all of the above and helps nobody.
