I am not a lawyer, but this doesn’t seem strong at all. How is it different than a person reading several books on a subject and giving a speech based on what they’ve learned? Obviously if the speech was repeating verbatim what was read, this would not be acceptable. But that is not the case here. Likewise, should the authors of books a child learns to read with be able to claim copyright over all works and language the child produces afterwards simply because their material formed the basis for that child’s neural network related to reading and writing?
