And a lot of people I know absolutely loved the game. Anecdotal statements are just that, anecdotal.
Source for the fanbase being divided? As for reviewers, when the verge calls Halo Infinite's campaign "very good" and polygon mentions that "Halo Infinite saves the series by finally doing something different", you can clearly see what I meant.
And by the way, I'm not saying your opinion is "wrong" or "invalid", I'm just challenging that the "division" is steep. It's not, and there was a lot of anti-sony bias when reviewing this game. This is not new, Days Gone got shafted even harder. People that didn't like this game (if you ignore the edgy teenagers complaining about Abby having muscles) are in the clear minority. Just read the bullshit reviews on Metacritic to understand that.
Metacritic aggregates music, game, tv, and movie reviews from the leading critics. Only Metacritic.com uses METASCORES, which let you know at a glance how each item was reviewed.

Most negative reviews there are from single users and I will bet most of them were paid astroturfers.
I'll reiterate - This does not detract from your criticism. But it detracts from the game dividing most fans. It didn't.
