All aspects of android (pretty much) are customisable. It’s not the os that is the problem, but the developers who program on all this telemetry.
There keyboards on android are much more useful than what’s available on iOS. There is a similar issue with launchers. They, by their nature, need more access to other apps and more permissions. In most cases, that means more features, but meta and Microsoft have launchers too…
I use android and iOS. I find both good but the customisable nature of android is what drove me away from iOS.
