> I've certainly tried: Firefox Focus was my main iOS browser for a few years (I know it's Webkit-based)
TL;DR The truth is, no one has ever used Firefox or Chrome on iOS.
You say you know it's webkit based... but the entire engine for any browser on iOS is Safari, not merely webkit based. Apple doesn't have a policy of "your browser must be derived from webkit" they have a policy of forcing browsers to use the literal same engine built into iOS that Safari is using - i.e you are just using Safari with a different UI, there is only one browser engine on iOS.
This is an annoying detail to have to repetitively explain to people, and Apple benefits from this blurring of the lines in the army of users defending them for browser diversity. Honestly, if i had an iOS device I would use the Safari app - and as a web dev and a user I fucking hate Safari, but what's the point in using a different UI, they are all the Safari engine, the main browsing experience is by definition the exact same.
