I only mentioned MS Edge to highlight that it’s a chrome(-ium) browser and therefore Edge probably has a paid team of developers.

That team probably has enough quantity of members (or coding work hours) to overwhelm the upstream chromium code contributions of volunteer developers of foss projects.

Because of Edge’s volume of contributions, they could accidentally/intentionally decide the direction of Chromium, even without owning it officially. That’s one of the ways I heard that Google controlled Chromium, accidentally or intentionally.

edit: wording mistake
