There are similar popups for Safari on iOS, and for Chrome when you use gmail on iOS. There used to be Chrome adds on the google homepage when you hit it with a non-chrome browser, but they didn't load for me when I tried it today.
I have never seen a safari ad and chrome ads on Google's page used to unobtrusively trigger for outdated browsers, which is arguably more relevant to the user.
The edge notifications look like a system alert and trigger constantly.
