I'm not sure about that, but a lot of it depends on what you consider to be "dissenting opinions".
I agree it depends on the definition. Quite honestly my vibe, and really that is all it is for any of us discussing this, is pretty much anything more aggressive than my comment above (or even including my comment above, once more people read it).
I definitely DO NOT mean clear hate speech, etc.. that's not my point at all.
For example, having the opinion that manifest V3 is good for users is an opinion that will not thrive on HN.
Personally I hope Tom will bring new moderation policies that will truly let unpopular opinions thrive, but I don't have high hopes here since this is just an announcement of a new moderator, not an announcement of new moderation policies.
