They are doing it in a clever way. They introduce this bullshit for big platforms, which are almost exclusively based on network effects. If it's useful, it's captured. If it's not captured, it's useless (the network effect is too small).
What is funny though is that it will almost certainly not protect the children. They will move to some unregulated platforms and the child predators go where the kids are.
How retarded does someone have to be in order not to see this basic thing. EU bureaucrat level retarded.
