What makes you feel entitled to the content of the publisher before the copyright expires? Do you feel that you deserve access to everything because you've deemed the concept of ownership around book publishing immoral?
You can't just take a digital copy of a physical book and give it to everyone worldwide. That isn't your choice or decision to make nor is it ethical to ascribe malice to simply retaining distribution rights to content they own.
"Make publishers richer", it's actually just honoring the concept of ownership...
If publishers didn’t engage in tactics like “library pricing” and preventing people from actually purchasing the books, I might feel differently. Right now, I see this archiving stuff as a Robin Hood story (which fwiw, every version of this story you may have seen/heard is probably still copyrighted) and I hope the publishers die or are replaced.
Internet Archive should focus on its mission of archival. Let other groups figure out copyright.
By taking on both tasks, IA risks everything and could stumble in its goal to be an archivist platform. We need an entity dedicated to recording history. IA is that. They're just biting off way too much to chew and making powerful enemies along the way.
By making the archive public, sure, we have a bit of a "piracy" issue. However, we can also verify they are actually archiving the things they say they are, point out mistakes, and ask them to remove things from the archive.
