First of all, you're thinking about it all wrong. Morrison is the one that gets the better deal here because his story is a part of the current canon and therefore will be more influential towards future stories, whereas this Kevin Smith book is now a glorified Elseworld.
Lots of the other bat-books have mentioned Inc, the organization if not the book itself. Morrison is known for being very secretive, you will most likely see Inc's fallout effect the rest of the DCU later on after the other writers know how its going to end. It's not insignificant at all, you just need to have some patience.
Also, I see no problem with the current Jason Todd being Wingman. It's not like both Inc. and Red Hood are taking place at the exact same time anyway, it's most likely weeks apart, and characters have juggled multiple identities before. And you're misunderstanding the "redeeming of an identity" quote. He was talking about redeeming Wingman's name, not Jason's. Besides, that conversation occurred in Inc. Vol. 1 so it may not even be canon anymore. It's an inconsequential plot point, in any manner.
And as far as Kevin Smith goes, he's generally hated in only one demographic, that being the comic nerds on the internet. As far as the general public goes, he's a popular celebrity and his name sells, no matter the medium. Either way, he's very influential in the business, so if he wants to write a comic, it's gonna happen, no matter how bad it is.
Best to just deal with it and not buy the book. Just think of it like Batman: Odyssey. It's may have been released post-Flashpoint, but it's not canon, so just enjoy the story for what it is.
