I think it's perfectly reasonable to have a conversation about whether we need to treat the major platforms as public utilities and force them to provide equal access. There are good arguments to be made on both sides and it's worth airing them. What I object to is your framing in the initial comment that it's unprincipled to oppose police suppression of speech but not oppose platform refusal to project speech. That's just the popular but mindless internet attitude of "anyone who disagrees with me is not just wrong but bad", and that attitude is far worse for public discourse and freedom of expression than anything the platforms are doing.
