Someone needs to create a zero knowledge crypthografically decentralized digital id, where the websites and platforms will only know if age>16=true and digitalid = official. If they where really interested in protecting children, that is. I belive it is the only option to correct this wrong. Play their game but present a privacy focused solution, and call their game. It must as well be open source for transparency with zero metadata collection.
If it really was about the children, this would be a solution that would respect everyone. But we all know that the children are just an excuse for control.
