yes, it is. Government pressured censorship at least. One can make a reasonable argument that YouTube is making the decision voluntarily. And the letter is just giving them some cover for what they wanted to do, based on their own biases, anyway. But private censorship is still censorship. And when a platform is so large that it has effectively become "the public square", well I do not go so far as to say that they cannot legally engage in censorship, but I do believe they are morally obliged not to, and should be publically called out when they do. I hope people will begin moving to other platforms in droves so that some real competition emerges.
