Technically that would make it expressly LESS secure. Is that your aim?

Regarding privacy, Apple does end to end on the vast majority of their services. Their servers are set up using a unique, physical key, that is then broken so once running, no one can get to the data.

Apps are sandboxed. Most every sensor or feature is gated behind a user setting to allow/deny.

But the most critical, Apple is a hardware company. The lions share of profits come from hardware. Google is an ad service/data manager. Probably one of the biggest reasons they dove right to amassing market share by licensing the OS to everyone outside Apple. It certainly helps their vested interests.

Trust whomever you like, but most things are true to their nature. Whether you want to believe it or not.
