I don't understand this at all. To provide children with a good education, you don't need Google search. You need a good teacher who will encourage curiosity of the students and some basic materials.
I don't buy this post. It's just assumes that what Google is doing is harmful so that people will feel good about Kagi. Maybe Kagi's policy is better, but that doesn't negate the fact that Google denying search to students is holding education for ransom as the title suggests.
Of course, it IS a bad thing that Google is trying to force everyone to use AI.
