1. The people working on these browsers are just that: people. They haven't necessarily been e.g. at Microsoft when IE vs. Netscape was a thing, and probably don't hold grudges. They were hired to work with the web, not against it.
2. There was a lot of duplicate efforts, and MDN was clearly "winning". That's a waste of time.
3. A more "neutral" MDN (although I think they've been doing a pretty good job already) is good for all browser makers. Even if Mozilla and its volunteers are trying to be a non-biased resource, they'll always be writing from their own viewpoint.
4. For Mozilla, MDN being less Mozilla-/Firefox-focused might not sound like a great option, but Mozilla's mission is to build a better, free and open internet, not to be dominant. (Incidentally, that's also the reason MDN "won": this made it able to attract many contributors and supporters.)
