The Internet Archive created a program they called "Controlled Digital Lending" (CDL) -- where a physical book is scanned, turned into a digital file, and that digital file is then "loaned" out to people on the Internet. In 2020, The Internet Archive removed what few restrictions existed with this Digital Lending program, allowing an unlimited number of people to download the digital copy of a book.
That was incredibly dumb. It's just baffling that they didn't run this by a lawyer or even a highschooler. They put all their good work in jeopardy for what exactly?
I still believe that serious hoarders who want to ensure other can access it should try to do so anonymously. IPFS, torrents, or something like eMule over I2P would be the best solution for this. Then copyright lawsuits like these would be very very very difficult to do without de-anonymizing people.
