I'm very pro privacy, but I'm just going to say out loud that it's not like US state and federal governments don't already have photos of your face that can be used to track you. The alternative is to hand over your ID, the thing the government printed after capturing and storing a picture of your face.
Did you know the TSA is a public branch of defense that sits between the DOD and the NSA?
I bet you didn't know that whatever data the TSA collects they can sell to corporations and back to the government for "validations".
the key is corporations can buy your private data from the government.
so yeah, this is a HUGE privacy issue.
if you don't support the product you must make it FOSS. been saying it for years.
