It was a pretty bad situations since some moderators have been instrumentalized for political purposes. And there is nobody that really called them out for it. This should have been the press and their silence is pretty loudly screaming about how you can depend on them. I don't care which political party was worse here.

We had content manipulation for political purposes. There is no guarantee that this will stop now, but changes were certainly needed. It isn't too great that it is now in the hands of Musk perhaps, but he at leaset has a different goal. Even if that is just a pretense it would still be an improvement. And no, some alleged bots are no excuse to just editorialize topics.

This inhibits people forming their own opinion if they will be fed with preapproved messages. So yes, it was a severe problem. Even European leaders called out Twitter when they banned Trump. And it was certainly not because they liked him.

I do believe that flagging is abused on HN from time to time. It just doesn't happen too often and HN isn't too relevant for public discourse. Twitter sadly is since a large part of journalism is about the latest Tweets people can be enraged about. Overall HN is tolerant of diverging opinions as far as I have seen.
