I believe that they were refering to the "or equivalent" portion of the phrase. Is not GFCI protection accepted as an equivalent level? I have no problem with this except the worry that I would have if I connected my computer equipment up on the GFCI protected 2-prong non-grounded system. Besides the worry of an unwanted trip, the static shock possibily destroying a chip would make this undesirable for computer type equipment, but, it would not be a safety hazard unless you were prone to throwing non-functional equipment at things.
