On Android, Google Play Store says "50M+ downloads" for Edge, while Firefox (which is not a hugely popular browser on mobile) has "100M+ downloads". So it stands to reason that the vast majority of the 3 billion or so Android users stick with the default, Chrome.
"Popular" isn't the right descriptor either, I have fielded many calls from relatives and aquaintainces that want "plain Windows" without the popup ads and Edge-y additions.
Doubt it.

Isn't Microsoft pushing ads onto the OS itself? If they are willing to show ads on the start menu, why would they block ads on Edge?
