That's a good thing.
Judging from the two video tweets I saw about the sign, its brightness at night was absolutely insane, lighting up the building across the screen with aggressive flashing/pulsing white light.
At this point the workers knew they'd get paid handsomely for 3 things:
1. The hardware itself.
2. Mounting the sign.
3. Unmounting it 3 days later.
Cha-ching. Client is always right, yes?
