Is it really censorship if the platform just isn't producing the output you requested? I understand "censorship" to be one agent blocking the ability of another (fully independent) agent to express themselves. In this case it seems more like an editorial board of a newspaper deciding what they will or will not publish, which is kind of a different beast.
