that information is as good as gone if its in the hands of corporation while they destroy the original. also, you cant get the original info back from the training data, what they are doing is kind of like putting the information in a blender.

and since they destroy the original books, no one else can have them. They also destroy piece of history since physical book is immutable while digital information can be tampered with. With rare books its possible they are destroying the last copy of the book, no way to know for sure.

And i'm already beyond pissed that they use others work for profit. It has already been demonstrated that corporations are above any law, as long as they can manage their bribes and connections. You should trust corporations as much as you would a demon if demons were real.
