Actually, the reason Android exists isn’t so one-dimensional.
- The company Android was initially concerned more with Microsoft dominating phones like they did computers at the time, before being bought by Google
- They created two prototype chains initially, one touch, one that was more akin to BlackBerry
- iPhone came out, they ditched the BlackBerry-esque one and focused on what became now Android
Google was mostly just doing what all tech companies were doing at the time, trying to compete in a mobile arms race for dominance. The data tracking was just a bonus. Appeasing shareholders is paramount. Look at how Apple created an Alexa speaker just because they had to as another example of this type of behavior.
Also, Apple actually has a long history of tracking user behavior that predates both Android and the iPhone.
Apple apps since some time shortly after the inception of OS X would (and likely still do) phone home to configuration.apple.com to send apple metrics on usage. Earlier variations of LittleSnitch could actually block this collection behavior.
Apple has since reconfigured the network stack to guarantee that direct encrypted connections to Apple are always possible above any VPN, or other type of network filter connection. So there’s no way to prevent communication with Apple on an Apple product at all now short of keeping it off the Internet or blocking DNS to 17.* IP addresses, which would only work on a network one has control over.
