For some licensing its not about how transformed it is but wether or not it was used.
Many of the books it read where not supposed to be in this library. The datasets used contains heaps of pirated content.
I repeat i am for abolishing copyright and legalizing digital piracy, including to train intelligence but if that wont be the case and piracy remains illegal then i want to see the “criminals” punisht. Nothing is worse in law then double standards that punish the small and leave alone the giants.
