I'm not trying to persuade you that your specific personal preferences for a "Safe Mode Internet" are wrong. I'm saying that just because you are
personally comfortable with Google's
current set of moderation choices, this does not mean that it is right or optimal for Google to start enforcing these preferences for society as a whole, particularly when it requires them to become the arbiter of truth and basic facts, while also avoiding the normal regulatory obligations associated with this. That is the slope we are on.
There is also a difference in kind between porn and this sort of speech. Different laws apply, different social norms apply, different technical options (and trade-offs) apply, and so on. I have also heard that there are many other porn hosting websites, and Google does not enjoy any sort of monopoly.
Perhaps we're talking past each other here but to put my general point a different way, and it's only relevant because Google is effectively a monopoly: If you were told you could be born into a world with a free internet, or a curated internet, but you had no influence over who would do the curation, which world would you choose?
