In order:
Wisdom can be interpreted as more than just deciding what is right and wrong, you don't have to be wise to decide that or be wise not to that.
I never said anything about him not having wisdom or him not ever using it. I was just as surprised as you that people are overblowing this. That's why (partly) I posted here.
Oh (out of order I know but this is important), and I honestly don't like the New 52 version of Billy. Can i live with it? Sure. But do I prefer him this way? No.
I wrote a blog about what I would like a Live-Action tv show of SHAZAM! to be like and I reference the two versions of Billy and how I would want the live action version to be like.
I said that I wanted a version that does like to do good but not overtly so and is withdrawn but not a jerk due to his life in the orphanage and foster care. Click

But to be honest I do prefer old-school Billy to new school. Is he more modern in the New 52 like I said? Yes. But I liked the heart-of-gold, that's what drew me to him as a character.
Oh and yes I'm saying that SHAZAM! may not be an acronym in the New 52.
