We are developing advanced communications environments. Our technology is used by many, many people. We are developing web-apps (PWAs) mainly because of faster update cycles and we only have to maintain one source. Our Safari users are already disadvantaged, because we can't send push notifications to them, we can't use background updates and more. So we are recommending Chrome whenever those issues comes up - though this of course only works on Macs and not on phones. I don't know why Apple doesn't put more effort into bringing Safari into sync with other browser engines and frankly, as a developer, I don't care. What I don't understand though: Why not allow "real" Chrome or Firefox onto your iOS platform? Why not let users decide which browser they want to use? Surely you must consider Safari to be top-notch or you would otherwise put more work into it. So - why not make it a fair competition across all of your platforms?
