Pretty sure that's the end result they're hoping for.
Blinding
I work as a repair tech for Batteries Plus, on the X and above what usually happens is a notification in the settings app about being unable to verify whatever part is an OEM part and that the service log for the device has been updated. If it's the battery that is being changed and it's not paired, it will lock you out of viewing Battery Health information, and if the repair shop doesn't copy over some data from the original screen then the replacement screen can cause the loss of True Tone. Haven't experienced a phone completely brick itself because of third party repairs but Apple certainly forces a loss of functionality simply because they want all repairs funneled through them.
I think they're a neat concept, but I'm also a device repair tech and they definitely seem to be more prone to damage. Had someone bring in a Z Flip 4 with the "glass" flaking away in the crease, have had people come in with snapped hinges or battery swelling popping one of the screens. The tech doesn't seem to be quite there yet imo.
I can definitely relate, I'm diagnosed with major depressive disorder and generalized anxiety disorder and this has been a daily experience for me for over a year at this point. So yeah, you are most definitely not alone.
Its going to be so nice to have Sync back
Considering some of their recent updates have bricked some models touch response (notably the Galaxy A53,) I'm not so sure seamless updates is a smart move on their part.
