I don't think anyone is really bagging on the list or anything, it's more that 50/50 is a very broad term. Especially in Injustice where you also consider cross ups are a thing as well.
Like is something a 50/50 if it's fuzzyable? Does it depend on how fuzzyable it is? Are tick throws 50/50s?
The whole spectrum is just VERY broad and I think a lot of people are confused since a lot of "50/50s" are fuzzy able in injustice, even if not at face value. Example A is Atro's classic F223 mix which isn't really a mix as we now know since it can be fuzzy guarded, but it's still totally possible to get hit by if you don't know the fuzzy.
