I'm in a similar boat. I bought an ipad because its simply the best tablet and actually gets attention. I didn't want a chromeOS or Windows device. The ipad for me is about 80% there and the other 20% is just not what apple wants.
If this would push that other 20%, I might even consider switching from Android.
As it stands, Android has a lot of free trash on the play store, and Iphone has a lot of paid trash on the app store because apple charges them hundreds per year for the honor of developing on their platform.
On Android, when I need an app with basic functionality, I already check fdroid first for a simple OSS implementation. I don't need my voice recorder to do anything except record audio. I don't need my heart beat monitor to do anything but check my pulse.
I'm hoping this change brings the type of innovation early jailbreak app stores brought that basically test drove features that Apple would copy years later and call "innovative".
You answered yourself. Most people are not Linuxy in the sense that they buy an iPhone and don't want to know how everything works.
