Who asked you?
I use my phone for banking, health tracking, Apple Pay and other activities that require it to be secure in case of theft or loss. Apple have developed a system that is superior to the fingerprint method currently used. The data used for facial recognition is, according to Apple, isolated to the device and not available on the cloud. Of course you may not trust Apple but that is your problem not mine. What fascinates me is how this is somehow creepy and immoral when Apple adds the technology but not so when other companies have introduced similar technology.
As for "privacy concerns" that horse bolted from the barn and was well into the next county the moment cameras became ubiquitous on cellphones. Anyone can take my photograph and post it to social media for the world to see. Many photo organising software packages now support facial recognition as a cataloging aid. For example, find all photos with grandma in them. In such a world it is trivial for someone to do a time-lapse of a street and pull out every photo that has a particular person in it.
No, it is not Apple or their implementation that is Orwellian and creepy, it is the world in general and we have to live with it.
