More services that cause automatic recurring revenue.

Last I checked, Apple has:

Apple Pay

Apple Card

AppleCare+

AppleCare Help Desk Support

AppleCare OS Support

AppleCare for Enterprise

Apple Messages for Business (not sure if this one is paid or free)

Fitness+

Apple TV+

MLS Season Pass

iCloud+

Apple News+

Apple Music

Apple Arcade

iPhone Upgrade Program

Apple Developer Program

Apple Developer Enterprise Program

Apple One

...and there are probably a few more I’m missing.

I’m surprised they haven’t figured out a way to charge a monthly fee for iMessage and FaceTime yet (beyond of course the usual nagging you for iCloud storage upgrades to store backups all of the attachments you’ve been iMessaged).
