It's even worse than that.Not using Apple's products is a good way to increase privacy. How ?

If you use Google's products(and who doesn't use Google Search ? ) , Google already knows plenty about you. And even if you don't use Google products, Google knows plenty about you, since it's tracking software is installed in large percentage of sites, etc.

And if you add machine learning on top of that , the amount that Google knows about you is great - even if you use Apple's products.

In reality, by using Apple's products, you don't gain privacy , you lose privacy - now two companies know a lot about you, instead of one.
