Nice eye — I did do remove that clause, but because the understanding in the industry is that the data shared with Guild members (for which there are 12k WGA writers and 100k+ SAG actors) can still be shared by those members. And even if they can’t, someone would likely leak them: good luck finding who broke an NDA with that many members!
I.E. They do not have to release the numbers publicly, but they’re not really bound by NDA either.
I imagine most, if not all, will go the direct route so they can spin the numbers how they want.
