I do not believe them at all. I do not believe they've had some change of heart regarding "many concerns about the place of facial recognition technology in society." I do not believe they intend to not use this technology in some other privacy-invading way.
Trying to figure out their real angle here. Avoid regulation? "Good" PR at a time when they desperately need it? A broader existential threat that I can't even fathom at the level of power their company currently wields in society?
Probably not much at this point they could do to change my absolute negative opinion of the company though, so there's that.
