Jason did his bit to get the SC out and that was after the release and success of Aquaman when he had the biggest exposure.
He also dunked on Johns, Berg, WB and that trade with the fake Frosty the snowman report last year. Surprise, mainstream media/trades lie their ass off too.
So I think he has done enough and WB probably threatened him with Aquaman 2.
Apparently he might get quizzed during Dune’s press junkets, so we will see what happens.
Him, Gal and Ben are probably taking the path of speaking up to get the goals achieved (2019 Nov) + (2020 announcement), and when the film is released, they let their work do the talking, and they don’t need to talk more publicly to rub Hamada and Emmerich on the face esp if Gal and Jason still have projects contracted to them and they need to think about their own team as well.
And again Ray Fisher is probably the spokesperson for all of them, the cast and the crews abused behind the scenes.
edit: we know Ben is tight with Zack and he is probably done with WB as well, so if even he is not talking, it means all that public gesture around the release is not that important. Why risk more wrath of big corps when a bunch of blue checks and press are doing the promotion and praising for Zack already.
It’s interesting for Henry to chip in tho in contrast, either he uses this to promote his chances of getting back into the cape, or he is done with WB as well, remember he was pretty quiet on D Day in 2019 probably still trying to negotiate with WB.
