While Meta's use of copyrighted material might actually fall under fair use I wonder about the implications of having to use the whole source material for training purposes...

Let's say I quote some key parts of a copyrighted book in an way that complies with fair use for a work of mine. In order to find the quoted parts I have to read the whole book first. To read the book first I need to acquire it. If it was simply pirated, wouldn't that technically be the main issue, not the fair use part in their service? I am an absolute layman when it comes to the subject of law and just thinking loudly. It seems to me that admitting using pirated works could be more problematic on itself, regardless of the resulting fair use when it is clear that the whole content had to be consumed / processed to get to the result.
