I would guess it is a mis-interpretation of the bolded section 4.8.2.1 (2014 manual) below

For safety and because of insurance regulations:

Teams cannot build any structure that supports people, or items for storage, above the workspace in their team Pit;
No team station structures, signs, flags, or displays can be higher than 10 feet above the floor;
Team station signs, flags, and displays must be securely mounted to the structure

While canopies are legal and many teams use them, I would personally caution against it... it makes pits very dark at most events. If you do use one, plan ahead for appropriate lighting!
