Lose.. to whom? PinePhone? Not trying to be flippant, but... there is no longer any option for the common user.
No, my elderly mother is not going to download and flash a custom de-googled ROM for her OnePlus 9 Pro. Pure fantasy that Apple will lose users because of this. This is a nonstory to everyone who lives and works east of Tahoe.
But you're right that some users absolutely do not care (or can only use Apple devices), they will now give up their right to privacy.
But you don't have to look that far to see that a lot of users disagree with what Apple is doing here.
No, instead they just scan everything you upload to their service: https://support.google.com/transparencyreport/answer/1033093...
And scanning for CSAM is certainly commendable, but the whole issue with Apple's implementation is that you lose your privacy on your own device.
That is a step too far.
