Development stories of X-T1 from Fuji

Why would the EVF adjust its brightness? Changing the brightness of overlay info is one thing, but shouldn't the image display reflect the brightness of what's being captured?

What I mean is that it should adjust the brightness level of the EVF, which is something different than the tonality displayed in the EVF. When you adjust exposure, what you see isn't the backlighting changing its brightness but simply the EVF displaying darker or lighter tones. Think of it this way : when you adjust exposure in Lightroom, it doesn't change your computer monitor's brightness. But if suddenly the sun bursts through the window that's in the opposite wall and reflects on your display, you'll want to increase its backlighting brightness.

When the EVF doesn't automatically adjust brightness levels, it means that it's likely to be too bright in darker environments and too dim in brighter ones, meaning that your eye will take some time to adapt to its brightness level and then adapt back again to the room's light when removing your eye from the viewfinder.

The Olympus OM-D E-M1 and E-M10 are the only two EVF cameras with this feature, and I find it very strange that Fuji didn't implement it since they already have the algorithm in place for the OVF info.

This is one of the key points to make an EVF closer to an optical viewfinder (which brightness obviously remains alway constant relative to the scene's brightness).
