My hill to die on: 343's bungling of the MCC was one of the biggest daggers to Microsoft trying to catch up to Sony. Halo has never been the same since.
Its made a very large improvement since launch, considering it now mostly works correctly. Its still bot perfect, but in all honesty it should never have even got to this point. Where it is now is how it should have launched.
343 was plagued by just awful leadership for ages. They've always have talented devs (just look at the latest MCC update!) but their "follow the leader" approach to the series' growth, coupled with a pattern of putting making cash over releasing a great game, was a losing strategy from the start. Good riddance to those folks.
