...and have everyone else who knows you stop, and block their widgets and buttons that track you, and block any org that might leak, sell, or just share some of your info with them. I can’t stop a friend or just some rando at a party from uploading a photo of me. I can’t stop friends from using FB and getting me into their system. In 2018, privacy isn’t just about what we choose to do.
I agree. But you should take that first step, and then start lobbying your friends to stop posting pictures of you. Personally, I also excuse myself at gatherings when the cameras come out, because I know it's all going straight to FB. The shaming has already started to decrease; now I'm usually not alone in popping out of the room.
I would be seriously impressed and surprised if they managed to get any information based on photos uploaded that happened to include people who weren't tagged and weren't on Facebook. Aside from the all-or-nothing nature of specific apps, privacy is more about what you choose to do than that - most people just choose to not do much for privacy. At least as far as most private corporations using the Internet goes.
However in this situation we are talking about 3rd parties having an all or nothing policy on your data. If you don’t let some apps you login with Facebook have access to everything you can’t use their app.
