Google never "sells" your data to third parties. They keep the data themselves for advertisement purpose. On the contrary, apple shares any collected data with advertisement partners. Apple fanboys don't realize this.
Apart from agressive and deceptive marketing, Apple is a shitty company that asserts patents on rounded corners of phones and optional chaining in programming languages (Swift). They are objectively more evil than Google in my book.
Apparently I am biased. I would not have been in CSE if Google didn't commoditize the market. My first encounter to programming was on an Android terminal. But that's another story.
