uploading that biometric data to god knows where
In the context of facial recognition, "biometric data" is just a picture of your face. If you've ever uploaded a photo of yourself to any website/service, then you've already lost that fight.
Edit: to everyone downvoting, explain why you think you know better than someone who worked in that industry and developed computer vision and facial recognition software for 10 years.
Edit 2: I think people are misunderstanding what I said. I'm not saying your photo "tracks where you are", but rather if your face exists anywhere on the internet (with associated info about who you are) then that's all anyone needs to build a facial recognition profile on you.
They just need to scrape various websites for the info and put it into a database. This is exactly what Clearview AI did. They scrapped Facebook and other publicly accessible websites and built a giant database that they then used to give police and other orgs access to via their software.
So my point was "think twice before you upload a photo with your face to any website or service"
