the writing seems to be on the wall for iOS only allowing WebKit-based browser rendering, with both Google and Mozilla publicly committing work on iOS versions of their respective engines
I would not be at all surprised if they have some NDA'd info about this from Apple about a policy change scheduled for later this year, where Apple want to be able to show off the other browsers on stage or something, so the work starts now
on one hand it's good that they're seemingly going to be dropping the de facto monopoly, browsers are broadly healthier when there are more of them
but on the other hand it feels like this rule was perhaps the last thing holding back a bunch of mobile web sites just saying "please use Chrome instead of your yucky choice of browser" just as so many desktop sites do already 🙃
