So why aren't they suing libraries for doing those "exact same things?" Why target the IA specifically, and not other libraries?
Could it be that the IA did not in fact do the "exact same thing" as libraries?
why you think that's something worth defending I don't know.
I am not "defending" the publishers. They are the villains here. I think current copyright laws are insanely overreaching and have long ago lost the plot of what they were originally intended for.
This is like a horror movie where there's a slasher hiding in the house and the dumb protagonists say "let's split up to find him more quickly", and I'm shouting at the idiot who's going down into the dark basement alone. The slasher is the publishing companies and the idiot going down the stairs is the IA. It's entirely justified to shout at them for being an idiot and recommend that they just run away, without being accused of "defending" the slasher.
