Uh, no. They haven't. We're having a discussion about whether or not there was a push, which turned into a debate about what constitutes a push in the first place. I'm not sure how anyone is getting the idea that a push is inherently negative. A lot of characters get pushes. The Guardians of the Galaxy got a push. Black Panther got a push. Ant-Man got a push.
I only mentioned that it was a "failure" in reference to people asking why a series like Death of the Inhumans was commissioned in the first place and to what end was the point of tearing down a lot of the stuff people like Soule had been writing.
