This has happened with the estates of famous people for a long time. It didn’t start with the current trend of deep learning modules.

Tupac’s estate has mined every single little recording he did and pressed it to an album. Gene Roddenberry’s notes got turned into two series (Earth: Final Conflict and Andromeda), both of which started pretty good and slowly degraded over time. The Tolkien estate was held back by Christopher for a long time, but now he’s gone, the remaining heirs are happy to rake in the cash, and they’re being thoughtless about what they greenlight (like the Gollum game) (oh, and there’s only about 20 years for them to keep the copyright, which isn’t that long; Peter Jackson movies were about 20 years ago).

Franz Kafka instructed all his unpublished manuscripts be burned when he died. GRRM has instructed that even if he doesn’t finish A Song of Ice and Fire before his death, it will not be picked up by another author to finish. These are wise people.
