Android is strange.
Google and the phone vendors only take on half the responsibility of publishing an operating system as you are pretty lucky if you get software updates never mind the kind of major updates an iOS device gets.
It is exhausting to explain to people how to scan a QR code on Android because the built in camera app doesn’t do it so they have to go to the app store and download some free QR reader that looks like spamscam and have a slightly different name every time you try it. (And no giving them a QR code to get the app.)
That’s the inattention to detail that pervades the platform and it is made worse by the outright vandalism of Samsung or Verizon filling up your home screen with lots of twisty little app icons that all look alike and certainly don’t lead anywhere you’d want to go.
Google doesn’t get paid for Android, Asian companies in corrupt economies seem to lose money making Android phones but there is some social status to be had by being a leader in 21st century technology so they do it anyway. Apple probably profits more from Android because Android keeps them out of trouble with antitrust regulators but Android is a ‘spoiler’ that keeps any real competitive OS out of the market.
Hypothetically Android keeps mobile safe for advertising but it is possible Google could be selling as many ads on somebody else’s OS without the expense and moral hazard of keeping a zombie OS ‘alive’.
