You're acknowledgeing and simultaneously ignoring the main point, in that the Federal Communications Commission threatened ABC's license over this. This is quite literally a 1st amendment/gov't censorship issue - not a platform simply enforcing their often shitty ToS.

And the main idea about pressuring these large platforms in the past about moderating and/or removing certain speech, was that the types of speech that folks were advocating to have removed was speech that quite often led to real-world violence when it was able to propagate en masse.

You can also see the same ideas here on Lemmy. Several of the servers that are most prolific in their spread of hate speech have been de-federated from most of the rest of the servers.

There are plenty of authors, journalists and anti-fascist researchers over these last ten years who've had the unfortunate job of wading neck-deep into the online platforms that DO allow that kind of speech so that they can document and track how those fascist ideals spread, and who is spreading them. THEY are typically the ones screaming the loudest about the need for some form of community based moderation and/or censorship of certain ideas.
