Maybe because you didn't observe it happening.

I did, actually. I made some of the John Brown posts lol.

Reddit admins were busy as hell cleaning the place up. All kinds of rightwing subs like some of the incel gathering spots. Some for straight up Nazis like frenworld or whatever it was where they were using honk honk as code for heil Hitler. When the admins made site changes due to complaints about right wing subs, Chapo made the list because they engaged in similar activities with the main complaint being brigading other subs.

Brigading is not an activity similar to supporting incels or Nazis.

I remember the subreddit mods sharing their attempts to communicate with admins on this, offering to make whatever changes would be needed, and getting stonewalled. The subreddit itself adopted a no-brigading policy and included it with an pinned automod comment on every post.

But this is neither here nor there because the ban announcement said nothing about brigading. Instead, they said it was about content violating their new anti-hate policy and a vague statement about mods not "reining" in users. Prior communications and the timeline suggested the only content violations were anti-slavery posts.

Their mods refused to change to meet the new rules.

How so?

The admins eventually removed some of the mods.

Which ones and why?

They still refused to change afterward

Such as?

The reality is that most of this was actually opaque.

When the sub was put on probation, the post Reddit cited was justifying violence against slave owners. As far as I can tell, you just made up that they threatened Reddit admins.

Huffman has been a frequent attendee at Burning Man, the annual, clothing-optional festival in the Nevada desert, where artists mingle with moguls. He fell in love with one of its core principles, “radical self-reliance,” which he takes to mean “happy to help others, but not wanting to require others.” (Among survivalists, or “preppers,” as some call themselves, FEMA, the Federal Emergency Management Agency, stands for “Foolishly Expecting Meaningful Aid.”) Huffman has calculated that, in the event of a disaster, he would seek out some form of community: “Being around other people is a good thing. I also have this somewhat egotistical view that I’m a pretty good leader. I will probably be in charge, or at least not a slave, when push comes to shove.”

Spez pretty openly fantasizes about owwning slaves
