Linking this explicitly to safe harbour like you've done is important -- the knee-jerk response online is often to condemn Facebook for not policing content but to defend content hosters for not being able to filter out all instances of copyright violations. Maybe those positions are held by different people, and maybe there's some good-faith "make an effort" middleground, and maybe the standards should be different because nobody dies when someone pirates Westworld, but they're clearly analogous. If we do have different standards we should be able to back it up with argument, and try hard not to let how much we like the companies colour our judgement.
