This is HackerNews. Either the top comment will support TFA and replies will refute the top comment, or the top comment will refute TFA. I can't think of a major story where that wasn't the case. That's kinda the shtick here.

Not just the top comments. Replies that agree are fairly rare here in general.

Personally I think that's good. Replies that agree rarely add new information, but they drown out other more informative comments and can create an echo chamber.
