Considering that you actually can't just uninstall Edge like any other program, since Windows wants to keep a backup browser, I think 98% of everyone who thought they uninstalled it really just deleted the desktop icon and changed the default browser.

I never uninstalled it, but I was aware I hadn't. I just used it to download Chrome, removed the icon, and moved on with my life.

Once Chrome can't block ads effectively anymore, Edge's job will change to downloading Firefox before being shelved.

I'll keep it around regardless, in case something doesn't work properly in Firefox. Plenty of web developers are lazy, and they develop for chromium based browsers first, these days. I'm sure I'll run into sites that don't work properly with Firefox.
