You are getting downvoted because, I guess, people didn't read who the defendents who are getting sued, and that it literally starts with sueing two employees:
CHANG LIU, TANG YEW TAN, OPENAI FOUNDATION f/k/a OPENAI, INC., OPENAI GROUP PBC, and IO PRODUCTS, LLC f/k/a IO PRODUCTS, INC.,
There are two individuals being sued, but many more received letters.
Parent is being downvoted likely because their statement implies the “dozens” receiving letters are individually being sued, but that’s not the case.
