In my experience, some non technical people often picked up the idea that "chrome is good" and they'll manage to install it.

So I guess you're right - the bottom tier sticks completely with the defaults, but there's a sizable 2nd tier that picked up the idea that chrome is good, and not much else.

Edge is a Chromium-based browser.

There are only 3 "internet browsers" in the world and every thing out there is a variant of them. CHROME, FIREFOX, and SAFARI

Default on the phone is the only thing that really matters anymore because literally everyone has a phone, usually multiple, and only half those people have a laptop or desktop. That's why in this graph Safari is in second place even though Windows cleans Apple's clock on desktop and laptop installations.

But I am surprised more people haven't jumped ship - off any Chromium browser, really. Once they really kill ublock give it a year or two before advertisers manage to do what they always fucking do - annoy the dogshit out of everybody - and you'll see people switching.
