> Microsoft would fork it within hours

I haven't trudged through Chromium's commit statistics but has Microsoft been upstreaming many contributions? I'm skeptical that they are ready to take on the full brunt of Chromium maintenance on a whim, it would take a decent while to build up the teams and expertise for it.

Before they swapped Edge over to use Chromium they were capable of maintaining their own engine just fine. Probably not overnight, but in the past they have shown that they have the budget to support a browser engine if they want to.

Why do you think they moved to Chromium then? They switched because they could not support a competitive engine by themselves.

Yes, Microsoft actively contributes to Chromium.

Microsoft lands many changes in Chromium first before they show up in Edge (logistically it's easier to do things this way for merging reasons), but they do also upstream changes to Chromium that show up in Edge first.
