Facebook is directly tackling complaints about its facial recognition practices for photo tagging. It's expanding access to its Face Recognition privacy setting (introduced in 2017) to all users, and will stop scanning faces by default. Those who don't have the setting will have to explicitly grant permission for it. You'll get a notice when the feature is available, but nothing will happen if you ignore the alert. Friends can still tag you by hand -- they just won't get automatic suggestions based on face recognition.
