Don’t get me wrong, I’m all for privacy. But between setting up the birthdate when creating my children’s local account on their computers, and having to send a copy of their ID to every platform under the sun, I’d easily chose the former.
I’d even agree to a simple protocol (HTTP X-Over-18 / X-Over-21 headers?) to that.
Wrong technical solution to a made up problem.
Governments have commissioned enough studies to know that education, training, and parental controls filtering content at the receiving end are more effective & less infringing of civil rights than laws imposing restrictions & penalties on website operators to comply with online age verification. Laws could instead allocate resources to promote the former in a major way, setup independent evaluations reporting the effectiveness of child protection technologies to the public, promote standards & the development of better standards in the industry. Laws of the latter kind simply aren’t needed & also suffer technical defects.
The most fatal technical defect is they lack enforceability on websites outside their jurisdiction. They’re limited to HTTP (or successor). They practically rule out dynamic content (chat, fora) for minors unless that content is dynamically prescreened. Parental control filters lack all these defects, and they don’t adversely impact privacy, fundamental rights, and law enforcement.
Governments know better & choose worse, because it’s not about promoting the public good, it’s about imposing control.
