When I took what little journalism I’ve had, the 5th W has “how”. “Why” was supposed to be left to the opinion page.
If you have an article on a murderer, don’t you want to know why he did it? What his motives if any were? If a reader is reading an article on a bond issue for a community swimming pool, do you think he’s interested in why the pool is needed in the community?
I fully agree. ‘Why’ is always subjective, and if you don’t know the other party’s stake in the game, dangerous.

Why are we attacking XXXX?
Why is Obamacare good/bad for America?
And any of a billion other questions critical to the understanding of an issue - AKA the reason behind it.
