A lot of the problem is reneging on previous privacy/data segregation policies. That is an entirely legitimate complaint.
There's also the question of to what extent you can opt out in the modern world. Got a mobile phone, pretty much essential to work or life these days? Your life is now beholden to Google or Apple. So yeah, people damn well do have a right to complain, and "just don't use it" is a fatuous thing to say.
Funny. Do you really think they're same? A company making money by SELLING PRIVACY, and a company making money by SELLING HARDWARE?
A company exists to make money. And all what they do is decided to make money. Which one would really have interest to take your privacy? Apple? That really doesn't help them to make money. They even tried, but failed. They're really suck at making money from privacy, and it degraded reputation of their product.
If you really think Apple is selling your privacy, tell me what's the REASON. How will they make money from it rather than losing their money.
Google? See what's happening now.
Why do some people always want to tie Google with Apple? Which makes money from completely different sources. The money source defines how the company behave. If you really know that fact, you really can't say that stupid tie up.
Your life is beholden by Google, not Apple. Someday maybe Apple does that - which is very unlikely happen, but not now. And the day will come after whole existing privacy sells - such as Google - are dead, so Apple dominate whole the market.
