OK that action allows them to do the transformation.

But how about the importing into the AI tool?

Does this "transformation" somehow override the authors complaints of AI taking their book and not compensating the authors for its mass usage in the AI tool.

Then, should we hope they do not do backups, as they would be duplicating. And that they delete the files (zeroing from the disk) when such books are loaded into memory as technically it would be duplicating also. The same if they use different machines simultaneously.
