Now, Google is not a public platform, and of course there is all sorts of awful content that is on a daily basis flagged and removed with objections that are justified. But you can see the direction this type of story is headed. First Google will be forced to hire people to do a better job of policing its sites, tasked with removing “extremist” content – and then there will be definitional drifts in how such content is considered extreme. What is religious speech in some parts of the world will be hate speech in some other parts of the world, and then the ability to use the platforms that have come to dominate the space will be determined by the priorities of the corporations involved.
You have the right to free speech as an American – you have no right to use YouTube to do it. And the mobs that exist can form very quickly if they are offended by your presence there. Be mindful of this in the years to come.
