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.
