I worked in a “datacenter” where the humidifier function for the HVAC unit was turned off because it leaked under the floor into an adjoining office when it was trying to humidify. Management refused to fix the unit due to the cost, and saw no issue with running the room with relative humidity in the teens all winter. Madness.
Static electricity. Humidified air dissipates static charges before they can build up enough to arc and cause damage to sensitive components.

That low? Wow… Your skin must have got chapped every time you went in there.
Yeah and too much is bad too, because it can condense on coolers. I’ve been told it’s also bad for bearings in HDDs when it’s too low.
Of course in a datacenter being low on humidity is a much more likely thing as there is nothing to emit humidity (e.g. humans).
