Why do (some) people reject all kinds of change?

[jameskilton]

This change has one important ramification that can cause confusion:

Github Enterprise has always had the black header bar.

If Github keeps the black header bar for both, it will be easier to accidentally be working in the wrong Github.

Now you said that, I wonder if it's a bug or a feature? :)

Sometimes the changes are bad

[dingaling]

Oftentimes because the change holds no benefit to them and they were not consulted. This creates a default 'change wariness' posture.
