There is no shortage of reactionary "tech people". They likely didn't think a bit about how this would work. Just ban kids from social media to protect the kids! And then their line of thought stops there. At the same time you've got people on HN asking for better parental controls. And when state governments push for exactly that, parental controls that still preserve individual privacy, everyone loses their fucking minds. Your operating system reporting an age range that you define so apps and websites can filter content appropriately is not a privacy violation. It's literally what people have been asking for. But this community wants to protect children from the internet and "dangers of social media" and also refuses to build any mechanism that distinguishes children from adults that don't violate privacy.
