OK, let me put it another way ...

iOS too ships with Google as the default search engine and just like on iOS, you can pick a different default on Android too. In fact Android has always allowed for changing all meaningful defaults, not something you can say about iOS. And in fact the world's leading Android makers, like Samsung, all of them ship with different defaults except for the Search engine (we're talking browser, email application, etc).

And all desktops actually ship with a browser that default to a search engine that tracks your searches, including Microsoft's Edge and their integration with Bing Ads. And Google is in fact the most transparent about what they track.

So if your answer is the Google Profile, which is transparent and can be turned off, then it's a pretty shitty answer. Unless you can point to implementation details in Android proper, all of this is just a conspiracy theory, similar to anti-vaxxing.
