Exactly!

All of this just smacks of the old, worn-out argument that "it's different because it uses computers!"

Editor is a literal career field, and has been for years and years.

Yeah, no, the writers of a TV show probably aren't random people off the street who are trying to sneak child porn past management. (Or not very often anyway.) There are disputes over how much edginess the writers can get away with, but in terms of the volume of content and adversarial nature of the relationship it seems pretty different?

This is like telling anyone and everyone to write and produce a TV station only for themselves then being surprised when certain illicit content shows up that you don't agree with. So no, it's not like traditional media content censoring (not to the same degree at least), but it is like modern global-scale media content censoring that already deals with hundreds of hours of content every minute (YouTube et al. having to hire moderators to remove CP).
