I agree very closely with Ryan, but I'd like to try an explanation I've been contemplating.
The word censorship is very loaded and I notice Tim Cook uses the word curated when describing Apple's App Store and Apple News. I think of curated when I think of Wikipedia, Amazon's book reviews, and The New York Times' comment section. It isn't that non-mainstream views aren't welcome and it isn't even about the political spectrum. It's about protecting thoughtful and reasonable speech.
For example, promoting pedophilia isn't political. But I think the vast majority of people want Amazon to curate their book inventory to include books about protecting children from pedophiles, counseling, and law enforcement, but not to sell books that promote it.
No one can come up with an exhaustive enough list of rules and no company can hide from the reality that they have to make judgements, not even 4chan. If they don't, many customers will deplatform themselves, as millions of people are now doing from Facebook.
So what is the answer and what will Cake do? I believe it has to be about values. I heard the editors of National Geographic say their values are to err on the side of facts, science, and the earth.
We value thoughtful conversation and human decency. It's what the world needs now. That means we'll have to keep trolls from silencing and deplatforming thoughtful people who have minority views.
