Re: Some intellectual property rights are more equal than others
1. Neither the freebie nor the commercial licences give access to the training data, only to - as you quoted - the generated outputs.
So that part of your question is, sadly, malformed. Indeed, given knowledge of the way that Meta were known to have used pirated materials - i.e. used with neither a business contract nor the simple purchase without need of specific contract inherent in retail sales - your line
> that using their training data without a business contract would diminished their ability to license their work
actually becomes inverted, as we know that the "their" whose (books treated as) training data without following *any* appropriate contract, that "their" disambiguates to the authors, not to Meta (by strength of reference).
IF your question is corrected to refer to gathering Meta's outputs instead:
2. Both sets of T&Cs are presented as clear contracts for you to follow and are covered by well-known and understood laws that everybody interacts with.
3. If one person was found to have broken a contract with you that does not prevent you from forming another contract with a different party nor does it mean you must necessarily lower your rates.
So that (modified) question is a "clear loser" (IMO, IANAL etc).
With respect to the point that the judge did make, consider this:
a. Meta's model ingesting the books does not mean no other model could be made to ingest the books; copies are fungible and provide the same potential value (however large or small that is) to all such ingesting; any difference in value realised is due solely to differences in the models, not the books.
b. Meta is not offering to supply cut-price (pirated) copies of their "central library" to other model builders (within the timeframe & scope of the author's complaints)
c. Neither Meta, nor any other user (reader) are claiming to have an exclusive-use contract on the books
So where is the hindrance to selling to other model creators?
(The only way I can see a hindrance would be if the author's are stating a belief that their works are/were *not* in any way useful, have no value and Meta's misappropriation have removed from the authors the ability to hide that behind extra terms - an NDA - that they wanted hidden in a business contract).
