No provider would carry all groups, and when you looked at particular groups most providers would not carry all posts.
But you still had some people saying that providers should do zero filtering at all, ever, and that doing so was evil censorship of the worst North Korean kind. Filtering was strictly something for users to do.
That's impossible for providers to do when people are using groups to distribute images of child sexual abuse.
Many customers were happy that sporge was filtered. Most customers wanted some kind of spam filtering, even using the very tight definition of Breidbart Index.
So there were conflicts in the userbase, which got pushed onto ISP support. Since ISPs were already paying for huge storage requirements I can totally understand this being part of the consideration to cut usenet.
Not carrying all groups is not the same as filtering. I'm sure the reasoning you describe exists, but it wasn't a very mainstream view. As a tiny data point, none of the ISPs I worked at saw this as a support problem.
