Don't quite get it

So apparently there's a remake of Ghostbusters in the making. It's a gender-switch, so it's got an all-female cast of Ghostbusters with a male admin of some sort.

Cute gimmick, I guess.

Back in July, io9 insisted on no longer referring to it as "All female Ghostbusters". To wit, I have to ask: why?

This is an obvious remake of an existing, successful film. There was an obvious move to replace the four male protagonists with four female protagonists (even down to the one token member of African ethnicity). Why not call it what it is?

It's a remake of Ghostbusters and it's got a female cast. This is what it is. It's not an original thing. It's a remake of an existing, successful film using a gimmick of swapping out the male cast with female cast. Sure, they may rock the roles and make this awesome, or even better than the original, but it's still a remake with very specific, conscious casting choices. Why pretend otherwise?

Sometimes io9 makes no sense to me.
