> “Your honor, we needed so many works that it was simply not practical to ask permission of the creators.” I don’t find this argument convincing given the ability today to license many content types at scale for TDM, including images, music and yes, journal articles (See “Full disclosure” above), but it is an argument often offered by infringers. Why is this type of argument even valid? Isn't this fundamentally sayi…
No, I think you're missing the "transformative" part.
The line of argument isn't "we're going to resell millions of codebases as-is for pure profit", which would be undisputed copyright infringement.
The argument is that something highly transformative (e.g. training models) isn't infringement at all, because transformative works are covered by fair use. And that, if we still wanted to explore interpreting/changing the law to force opt-in for highly transformative things, it's logistically unreasonable, to such an extent that the transformative thing couldn't occur at all. So that it's a waste of time to even be discussing asking for permission as some kind of potential compromise or requirement. If it's transformative and therefore fair use, asking for permission is an irrelevant distraction.
That's why this type of argument is valid. I'm not saying whether the argument will/should win in this particular case, but I'm definitely saying there's nothing absurd whatsoever about it.
