Even if you believe in objective morality, I think my point about how the discussion should go stands. Let's say that your definition of free speech is the objectively correct one. You then have to convince people to adopt that framework. You can't appeal to the objective definition; that's a circular argument. So you have to do it on the merits of the tradeoffs, like "bot spam is noise that detracts from a conversation". To your example specifically, my own opinion is that it depends. I'm fine with removing bot spam from a comment section. But move down to more "infrastructural" layers, and I become less okay with it. For example, I don't think ISPs should try to block spam; they should be entirely agnostic to what content passes through their pipes.
