Personally I think everyone just wants to find a scapegoat when things aren't good instead of putting the blame on Tony lol it's kind of the opposite of when something good happened in WWE and it was always magically something Vince had to be forced to approve.
They did it with Cody first and outside of booking himself to never challenge for the world title, I don't think any of the CodyVerse was very much his creative, Tony said he took full control after the first year because he didn't like how some things played out that he let others handle creatively so that means good and bad it ends with him regardless of who may have originally pitched it, their vision may have only inspired the version we see on screen which was from Tony's interpretation
