But why is this invalidated by allowing allowing the user to install software from other sources, allow a the user to install a browser that is not a skin on top of safari, allow non apple game streaming services on the platform, allow the use of images/text that mentions or shows competing software company logos/names, allow apps to show price differences in payment processing or allow established payment methods like PayPal to be used on the platform.
If would still allow the same user to only use apple pay or the apple version of their loved service of choice but also gives users that don't alternatives.
