Same reason Google forked webkit to make blink. Over time the involved parties' priorities diverge and when that gap is wide enough, it makes sense to fork.

Also note it's not just Edge we're talking about. Microsoft is one of the main Electron stewards, and products like VSCode are built on that platform.

As I said, I'd like that to happen, but I don't see MS being bothered by diverging priorities enough to fork after _throwing away_ a whole engine to avoid duplicating work. At least not in the medium term.
