Many HNers have a weird belief that Apple is somehow a privacy focused company, despite it actually being no more private than Facebook or Google.

The main concern people have (voice assistants beside) is data gathering for ads, which Apple does for their app search, among other places. Also, their data centers are in China, which gives Chinese authorities full access to their iCloud account.

If you want privacy, don't rely on corporations. Host everything yourself, and encrypt your data at rest and in flight.
