It's actually quite simple: follow the money.

Apple makes little to no money by invading your privacy. They've already made money once you bought their hardware. Which is why they will be a much better champion of your privacy.

However, companies like Google and Facebook make almost 100% of their revenue by knowing every detail they possibly can about your life. That's why they try to commoditize hardware and place all the value in your personal information.

Just because it is not a primary revenue stream does not mean Apple lacks a profit motive to collect the data on their users.

They certainly do. And since I cannot audit any of their upper layer code for any of their products, I cannot have any faith that they don't.

At least with Android, I can get my own spin on AOSP like Paranoid Android.

Facebook doesn't commoditise hardware - but otherwise you're right. However, for hundreds of millions of people buying their first smartphones iProducts isn't even a viable option, while a sub $100 Android phone is. And those devices will be their gateway to the internet. So maybe something good will come out of it too

And I guess you can opt out of the Google tracking ecosystem even on "Android" hardware
