Please mark sarcasm at least with a ";)" otherwise many people might think you mean what you say becaise they don't know that it's a ridiculous idea that a big corp will come and protect each users privacy.
Google's business model, in broad strokes, is selling user data to advertisers.
Apple's business model, in broad strokes, is charging consumers premium prices for hardware.
As long as Apple thinks the market values user privacy, they are economically incentivized to provide privacy- and security-focused software features that get people to buy their hardware over Android equivalents.
Is that an irontight guarantee? Of course not. Is it a (current) alignment of incentives that means Apple is categorically more likely to protect privacy than e.g. Google? Absolutely. That's also played out so far in practice, between things like app security sandboxing and Apple's historical unwillingness to help law enforcement decrypt encrypted backups — see e.g. the San Bernardino shooter case.
I actually pay more for an iPhone to be in their walled garden (with all the restrictions therein) for the better security and privacy. I consider my smartphone to be an appliance and am ok to trade-off uber-customization-capabilities for better than Android level of security. I also carry an Android phablet for on-the-go mobile hacking/coding/exploring shenanigans, but don't keep any data on it for obvious reasons
The walled garden is great and protects my privacy.
