Every service may be abused to spread misinformation. Here, the complaint isn’t that people abuse a service against the owner’s will, but that the service is operated to spread misinformation.
One way to address this could be to look at moderation. Is there meaningful moderation to limit misinformation? A service operated to spread misinformation wouldn’t moderate it.
He’s also giving more material to the CoC board by posting this. He’s free to do it but it’s not helping.
I wish he would avoid commenting and stay away from the drama, until he hears from the board if there’s any complaint and what it is.
