Is this serious or sarcasm? They passed a horrible law, now its an internally contradictory horrible law because apparently it isn't important enough to consistently enforce. So, you know. Why legislate it?
There isn't much of an angle here that reflects well on Californian lawmakers, they're still supporting this authoritarian trend of de-anonymisation and rolling back free communication on the internet. They're just going to come back for linux later once the idea of legally mandated PII on account registration is normalised. Although I do see this "In addition, lawmakers inserted a new provision prohibiting anyone from requesting an age signal from an OS provider or app store unless required by law" so we seem to be entering a wild space where they're going to try and micromanage this in a weird way.
