Hmm, but the only conceivable defense Meta has in this action is "Fair Use" under copyright law.
The number 1 criterion under Fair Use - and, typically, the one weighted the most by judges - is precisely Purpose and character of the use, including whether the use is of a commercial nature or is for nonprofit educational purposes. So, this one goes 100% to the authors.
It also strong supports bs's point, that using "content for business purpose, i.e. to make money" is one of the places where the line is drawn as to whether it is copyright infringement or not. This is, indeed, one of the lines.
Just for the curious, here are the remaining 3 factors in determining whether a use of copyrighted material can be considered "Fair Use":
#2. Nature of the copyrighted work. If it is highly creative this weights against fair use; if rote or formulaic (ie, a telephone book) it weighs in favor. Since they copied literally everything, including many novels, poetry, and other highly creative and individual works, this factors strongly favors the authors and disfavors Fair Use.
#3. Amount and substantiality of the portion used in relation to the copyrighted work as a whole. They copied the whole damn thing for every work, and an incredibly vast amount of works as well. This factor, too, strongly weights against a finding of Fair Use.
#4. Effect of the use upon the potential market for or value of the copyrighted work. Since the end result of this copying is the creation of a machine that can essentially replicate various others voices and works, this also weighs very, very strongly against a Fair Use defense.
It is hard to imagine how Meta wins this one. If they somehow do, their lawyers have definitely earned the hundreds of millions they are going to charge.
