It wasn't a rant. It was an answer to your inaccurate "reason."
its not entirely innacurate.
Google has moved the core of their services to an App model, rather than built in directly into the OS.
This includes the Photo and camera, Google now, email, browser, Calender, phone, clock, Contacts, Docs/sheets, Google Drive, Fit, Keyboard, etc.
these are all able to be replaced, upgraded independently of what version of Android they are running on. This gives google the ability to provide many of their services and software backwards to older devices, even if those older devices don't run the latest version of Google.
That means, your Android 4.2 phone, might be forever stuck at 4.2 because Sony decided that after 6 months, they weren't going to update your phones OS anymore, But, you still have access to virtually all the google services that someone on 5.0 gets. This renders knowing what version of Android you are on, to be less important.
Where, on the other hand, most of Apples applications that are shipped are bundled into the OS itself and often do not get updates till the OS gets updated.
