The algorithms are tuned to vastly extend the time users spend on a network. They are going to moderate stuff if it improves the time spent on that network. Of course there are political reasons for which algorithms also do content filtering and censorship but the money reason trumps all: the more time you spend on a network, the more ads you see, the more time you spend on a network, the more content you produce and the more you interact with others and that produces a smell that will attract other small insects which will be served ads, will produce more content and interaction.
