The article explicitly mentions the Tom Waits case did not include a copyright component as he didn't own the copyright, and Frito-Lay probably obtained synch rights from the copyright owner.

Part of being a good lawyer is sometimes "well, this didn't work in 1992 (or whatever) but it might fly now. Let's try it, worst case is X". And, as always, the devil is in the details.
This one is unique because Hauri (aka "Yung Gravy") is another music artist. The Midler case is actually mentioned in the court filings, too.

I'm pretty sure this is exactly why TFA was posted—apparently you can, in fact, protect a voice under California law. Of the $2.6 million in damages awarded in TFA $2 million were for "voice misappropriation".
This seems to be the relevant section of the civil code:

My take is that for a certain cohort of AI hypersters and Sam fans, it is literally impossible for OpenAI to do wrong. Sam could probably shoot a man in cold blood on national television and we'd have somebody explaining how technically it's legal because reasons.
Any other examples? Not trying to defend OpenAI just interested in this idea that it has actually made anyones lives worse.
