I doubt the amount will be anything near that figure as these class action suits usually involve only small token payments. I got a notice of four books where I am the translator. I have no idea what they will pay per book for the authors, much less the translator. If I get any payment, I will keep it as I was paid only 5 cents a word to translate these difficult books published by Yale University Press, at a time when the going rate was 10 cents. And the authors worked hard on their research with a lot of archival documents now no longer accessible, and likely they will want to keep their compensation as well as you never make much on academic works.
It's ok to get paid for your work, and if AI slurped it up to help make billions for that company, it's more than fine to get some just compensation for that slurp without permission.
I think all the platforms have to make it easier to both give consent AND ask for a payment, even just a tip, from readers. Not "Creative Commons" which is designed to work AGAINST legitimate commerce by content creators but an automated system where permission, payment, and tips can be made. The big platforms resist this because they want to keep ads and subscriptions as their business model. All you're doing is keeping alive a business model that is in fact a failed one for most people, creators and users. Be bold and future-oriented and advocate automated micropayment systems.
