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.

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.

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
