Maybe that arrangement led to the stagnation of Firefox, without malicious intent from any party. Hanlon's razor, yadda yadda
Once you get into corporate politics it's the exact opposite.
God help you if you ever get into the nuts and bolts of governmental, or gasp intergovernmental politics.

Edge is available on Windows, Linux and macOS, so it would probably do. But that would allow one of Google's biggest competitors to drop an under-performing product and lobby for antitrust against Google. Unlikely to happen, but a risk Google might not want to take.

There's such a marginal difference between the quality of the two browsers, and Chrome is held back in what it can be by the necessity of furthering Google's commercial interests. The only limit Firefox has had is that they can't abuse the trust of their users. Firefox had to voluntarily (and often aggressively) inflict a huge amount of reputational and functional damage on itself to reduce its market share to the place that it has.
edit: it's important to say that they didn't really backslide technically; it's user-hostile (management) decisions that have hurt the browser, not anything to do with the skill of Firefox developers.
Firefox is the only "credible" competitor, although Firefox's only profitable customer is Google itself.
IIRC, didn't Mozilla lay off some R&D team that was doing some promising work on modernizing and improving its browser engine?
It is questionable, and being declared a search engine monopoly would be far worse for Google than Chrome being a browser monopoly. They only make Chrome to push their search/ad network.
So they spend all of Mozilla’s money on various BS like Pocket and now VPN to try to make more money so they can further increase their already high salaries, instead of reinvesting into Firefox - hence the anti-user intrusive ads, the reduction of head count while paying themselves millions of dollars.
