I am not claiming that there is a simple solution for how to handle censorship that is optimal for the benefit of mankind. I am saying the way companies should approach implementing it is relatively straight-forward.
Otherwise you'll have endless debates about what is and is not moral, where nobody will ever agree and product managers and engineers and everybody else will constantly be in tension and nobody will be happy.
Censor as little as necessary based on laws and let people make their own decisions for what they want to view.
I don't really "get' it either.
But that's not what the issue is here. Displaying CP is literally illegal - was discussing homosexuality illegal? Was viewing nude males? It's the difference between blocking the literal illegal item or blocking items adjacent to it.
These are weird comparisons to try to make.
Discussing CP is legal. Viewing it is not. Viewing homosexual pornography has been illegal in the past. Viewing nude males wasn't illegal, just like viewing nude children isn't necessarily.
Legality isn't always the best way to draw a line.
