I think it's more that Birdwatch/Community Notes, which gets a lot of feature-love from Valley types, is already being weaponized to the point of failure. In the absence of any other moderation, this is leading Twitter into a dark descent of increasingly moderationless content.

Community Notes is just a subset of rank-based comment systems (e.g. Reddit and HN), and these are known to fail over time due to the commodification of votes. Even now you can go on certain forums and purchase a Community Note for a post for some hundreds of USD. It's not a substitute for moderation and everyone knows that if Hackernews defaulted to it instead of relying on dang that HN would fall apart.
