They allowed some company to track users (I don't remember which one but if i had to guess micrososft) it was a big thing at that time and they came out and said it was only for the people who used their mobile app and not the search engine . But come on they had to wait till someone caught them to come out ? That breaks some trust like how do we know right now they aren't pulling some shit and will come out with an explanation tommorow when someone catches them.
