At Disneyland, there are separate park entrance lanes that don't use facial recognition software. I like that I can opt-out passively there.
At TSA checkpoints at the airport, you have to actively ask to opt-out.
I'm always worried that actively opting-out puts you on a government list and there could be later, much larger ramifications, so I passively opt-in to blend in with the masses.
Last time I opted out at the (edit: TSA) scan, a number of people behind me followed suit.
I enjoyed that. I will remember to opt out again.
I don't see the point of opting out at an airport, of all places. They already know (or should know) the real names of everyone who's flying. Fully agree that facial recognition at an amusement park, or any private business, is egregious.
Yup. Most people are going to say "I have nothing to hide" and go with the flow. The ones who don't are signalling that perhaps they do have something to hide.
