I'm not sure what more they could do. They're extremely pushy about it in Windows. It takes several steps to make it stop pushing Edge when you open any web links.
I don't use Edge (or Chrome) because I don't trust the companies that make them, and it's one small piece of my computing life I can withhold from them. So...there's nothing they could do to make Edge good enough for me, without fixing the lack of trust I have toward Microsoft, which I guess is a marketing problem, but also a behavior problem. (Surprisingly, though, I think I feel less animosity toward Microsoft than I do for Google these days. Which, is hard for me to believe about myself, given how long and how much I've hated Microsoft over the years.)
