Earlier quoted context omitted.
For me, "an iPhone that complies with these demands" would be a worse experience than the current one. I have no intention to install Microsoft app store (so I can get Outlook), Facebook app store (so I can get WhatsApp), and Google app store (so I can have Maps). I prefer having one app store to having four different ones.
You can use any store you want on Android, and yet you can get Outlook, WhatsApp and Maps from the Play store. Why would it be different?
In the future, this might be the same on the other platform, — or it might be different. I don't trust any of Google/Microsoft/Facebook to not try to shove their app store (user account, personal information collection) down our throats in perpetuity.
