I'm on iOS and the biggest downside to iOS in my opinion is the $100/year developer fee, the Mac requirement for development, and the lack of side-loading. What this ultimately means is that it can be hard to find free / open source apps for iOS, especially ones like newpipe that might not be approved on the App Store. It's honestly a pretty big bummer. Some other restrictions also mean that Safari is pretty much the only viable browser on iOS and ad-blocking / extensions are fairly limited. Another disappointment is that ad-supported apps seemed to be a lot more annoying than the Google equivalents, weirdly enough. I guess Google maybe has more / different guidelines about making ads supremely irritating, or maybe I just had better options for free apps on Android.

I'm curious what you mean by "in light of what Apple is doing"? As far as I know iOS isn't really miles ahead of Android in any particular area -- they're more or less comparable in my experience, with iOS being a bit more limited in terms of customization and stuff (the fact that you still can't place icons anywhere you want on the homescreen is baffling to me).

If I'm being entirely honest, I think I probably like the Android operating system more than I like iOS... Which is weirdly part of the reason I like iOS -- I'm a little less tempted to look at my phone and a little less tempted to tinker with it. And there are are things that I like about my iPhone. The hardware is nice, the Apple Watch is really nice, FaceID is great, some things I thought would be silly like live photos are actually kind of nice, some of the iCloud features are great, and it's nice that it pairs with other things in the Apple ecosystem well. Ultimately the main reason I've abandoned Android is that I just got sick of my Android phones dying all of the time and only getting software support for like 9 months. Apple's support window is massive in comparison, which is also a big plus.
