Censorship is a blunt tool, wielded for different reasons, with stifling unwanted intents/desires/thoughts from the populace being a desired outcome. Dictators will dissuade rebellion/revolt/disloyalty. Clergy want you to stay faithful to their religion (and power), so dissuade blasphemous thoughts. And parents wanting to be lazy and have the schools do their parenting for them. And while it may have collateral damage, censorship exists because it can be effective in some situations, delaying the inevitable (and that can be good enough).
Overall, I like AFF because it’s generally supportive of freedom in writing, and the few rules that do exist are to starve the lawyers. Because, like you, I loathe censorship, that’s why you’ll see the topic appear in my stories from time to time.
