I agree that Apple does not have a reputation beyond reproach and your criticism is valid on all points. However they do have a consistent track record of putting more power and control in the user's hands in terms of privacy, security and controlling access to their personal device. So I do recommend Apple products to overwhelmed parents and older relatives that I would otherwise have to spend hours supporting.

Quick google search (that apparently I've been to several times before) points me to a list of options on how to cancel subscriptions: https://support.apple.com/en-us/HT202039

But you are right that it takes more work to stop paying them money, that for example to swipe on the home screen and disable all push notifications from Facebook. The latter being something that doesn't impact Apple's revenue.
