Really!??? To me that’s as if ‘white balance’ was taken to refer to someone with white clothes balancing on a step ladder. I fail to see any connection whatsoever.
That sounds critical which wasn’t my intention, I’m just shocked into incredulity.
My take on all this is that exposure is the correct term. As has been said already, it’s the same effect as adjusting ISO in camera, and as such also simulates a change to in-camera exposure.
As far as I’m concerned there’s no room for improvement, regardless of beginners or professionals.
It’s completely and utterly the correct term… 
And I know the original question was not about changing the name of the control - I don’t think I can help with that question though.
