"What point are you trying to make here? iOS users have no choice but to use Safari."
Android users use the browser on their device -- any browser -- less than iOS users use their browser(s).
Read the Google corporate propaganda repeated on here, and other platforms provide a web bliss of PWAs, freed from app subservience. Only, not at all.
Can't harass users with notifications.
Safari can open a pdf up like a native webpage in a tab. Until one of the Android browsers can do this out of the box (without having to use a ridiculous fork of Firefox so I can install extensions Mozilla doesn't want me to and installing pdf.js extension to use their own project), it will always be the superior browser.
I have not seen such a great community on the internet before, so if you have any recommendations of forums like HN, it would be great!
