"Let's ban children from using computers to exchange information!" is the wrong solution to the problem of "Sillionaires have enshittified our computers so much that they're measurably hurting children".

#enshittification

And if one's reaction is "No, we can't ban sillionaires, we've got to ban kids — sillionaires are too powerful", then, well, you'll know what kind of bully one is.
