@uis I believe the lawsuit was about their lending scheme, where they would "loan" out copies of books they owned (which were still restricted by copyright), one at a time (although during the lockdown they removed the temporary "one copy" limit), for a limited time and then that copy would be deleted - enforced via digital handcuffs.

I don't believe the authors of such books had any complaints about such copies being made (many now long dead) - the lawsuit was filed by publishers (who most of the time demand that authors surrender their copyright and only care about what profits they imagine they're going to get by restricting books) and it was presumably about how any copies of the books were being made at all - but I'm sure they were somewhat relieved that the copies were handcuffed.

The internet archive also has copies of books now in the public domain and those can be downloaded without handcuffs.
