Because I dislike the implication that only Apple is doing it. No. Everybody is doing it. Apple was just the first to publicly admit it. Doesn't make it better, sure, but let's not delude ourselves at least. No company can resist using all that valuable personal data on the smartphones.
The fact that you only mentioned Apple makes it a safe assumption that you only meant Apple. I chimed in to specify that I believe everyone is doing it, and let's stop at that. There's no prize to fight over here.
It’s an article about Apple so I only mentioned Apple lol. While we’re at it we should mention Microsoft probably does this too. Probably Snap as well.
