During the pandemic IA announced the National Emergency Library. Theory was so many books were locked in closed libraries it was fair for them to decouple from their physical count and make all their books available for unlimited digital download. The publishers responded by suing, and basically threw the book at them.

I don't agree with the publishers opposition to CDL, but it's disengenous of IA not to mention that nobody sued them over it until they went much further.

Edit: And when they first announced the NEL plenty of people pointed out that their announcement was heavy on ethical arguments, light on the law, and threatened to blow up an ok status quo.
