Everything you allege here is misinformed as to the current state of the lawsuit and stakes.
You demonize Hachette et al (4 major publishers) as seeking to destroy a public good. In fact, they've already settled with the IA, as of last August 2023, in a manner that caps costs to IA at a survivable level and sets clear mutually-acceptable rules for future activity.
You imply IA would dismiss the appeal if the plaintiffs "could drop enforcement of the judgement". In fact, there were never any assessed damages, the parties have already reached a mutually-acceptable settlement per above, and despite that – in fact, as part of the settlement! – the IA has retained the right to appeal regarding the fair-use principles that are important to them.

>On August 11, 2023, the parties reached a negotiated judgment. The agreement prescribes a permanent injunction against the Internet Archive preventing it from distributing the plaintiffs' books, except those for which no e-book is currently available,[3] as well as an undisclosed payment to the plaintiffs.[25][26] The agreement also preserves the right for the Internet Archive to appeal the previous ruling.[25][26]

>Because this case was limited to our book lending program, the injunction does not significantly impact our other library services. The Internet Archive may still digitize books for preservation purposes, and may still provide access to our digital collections in a number of ways, including through interlibrary loan and by making accessible formats available to people with qualified print disabilities. We may continue to display “short portions” of books as is consistent with fair use—for example, Wikipedia references (as shown in the image above). The injunction does not affect lending of out-of-print books. And of course, the Internet Archive will still make millions of public domain texts available to the public without restriction.
