This seemed already at the time completely counter-productive and unnecessary step as it basically forced the publishers to react because it made IA's digital lending indistinguishable from casual e-book piracy.
They have now created a legal precedent that, in addition to finding the "National Emergency Library" illegal, makes the controlled lending they implemented previously illegal. Ever since the district court ruling they have been able to continue digital lending only by negotiating compensation terms with the publishers.
So, instead of expanding everyone's access to the digital archives, they have managed to indefinitely limit it by creating a restricting legal precedent. This was the inevitable outcome of "National Emergency Library" and they knew or should have known it.
