Rambling, independent, non-DST-spokesman thoughts:
I do think there has been a shift in culture in the US to not appear exploitative. If Zendaya wants to dress like a Sorayama robot, she can, but to try and sell an image (or toy) of her dressed like a Sorayama robot is iffy.
I would not blame Disney for this -- they are going ahead with a new Deadpool, so they clearly see that there is a market for adult-oriented material. And I'm sure Fox will continue to make R-rated films. And the Marvel movies will I'm sure continue to feature PG-13 material, including that Eternals love scene and plenty of gunfights.
BUT comics have a long history of backlash against adult content when they are marketed (in the US, overwhelmingly) for kids. Obviously, there is a market for adult-oriented comics, and DC even has their Black Label books, but Marvel's MAX line seems to be a distant memory. I remember just a few years back they got Milo Manara to draw some Marvel covers, but one cover of Spider-Woman saw some backlash because she appeared too submissive/sexualized.
And toys... remember when they put Breaking Bad toys in Toys"R"Us? Toys are for kids, and if they are in a toy store, they are going to be seen by kids. Licensors that exclusively sell to older audiences don't care, but family-friendly companies want you to make family-friendly toys. Even with Black Label, I don't think we'll see anything risque coming out of McFarlane's DC line.
...Any of that make any sense?
I mentioned Dazzler, because she has some cleavage that probably wouldn't fly today. I remember once a blogger called us out online about our Stargirl MM for having a highly defined chest. I was actually confused, because at the time that figure was like 5-6 years old and we had JUST released the Lady Death set.
