No need for hyperbole.
The point you are missing is that those books get consciously thrown in the trash. Somebody evaluated them and decided they weren't worth saving. Will some fraction of these be the result of poor taste and those books were indeed worth saving? Sure. But most it's reasonable to assume won't be. In any case, they will still have been deliberated on by an actual human being.
By contrast, these AI companies are doing none of that. They are blanket buying books, scanning them and then pulping them. No human evaluation happens at any point.
