i could really see it going either way. apple likes to pander to the developer crowd, and they also like to have a consistent and streamlined operating system. both of those things would be strong incentives to roll out the changes worldwide. (many in the “developer crowd” would probably want access to third party app stores and non webkit browsers, and many people who don’t follow technology closely might be very confused by things like the firefox app being fundamentally different in the EU vs US.)
depending on how the laws are enforced, people could also theoretically switch their phone region to the EU in order to download those apps.
although apple also loves to have control over their operating system, and they have a pretty large market share in the US. i doubt they’d love giving up that much control.
It's not really "going out of my way to dig at Apple"
There's little reason to use any other browser on iOS because of the policy they enforce. If all you're getting is just Safari with a different face, you're literally making your browsing experience slower and worse. Some people don't know this so my comment educates them on such.
Firefox doesn't support extensions on iOS. As it's currently impossible. Due to Apple's restrictions forcing the use of WebKit, this makes Firefox (Gecko) extensions incompatible. Additionally, Apple's own extension system for WebKit is proprietary. https://support.mozilla.org/en-US/kb/add-ons-firefox-ios
As far as features go, what can't natively be done is handled with JavaScript injections. As WebKit allows you to do this. Since it's locked down most take advantage of this. Naturally, injecting several functions can slow down the web experience. About the only feature IMO that will matter to most people is the ability to sync content. Such as passwords and browsing history.
Idk why the other guys saying it’s some edge browser. This is the google app on iPhone. The bottom part pops up when you click on articles because they’re pushing their AI summaries. It’s actually a great feature but it’s annoying how much space it takes up
