In terms of injury risk, there is a significant difference between having a phone out on Pirates though and having one out on a Velocioaster level of coaster.
Second, the example you linked happened on Busch Gardens' Iron Gwazi.
Third, nothing in the article says the phone owner was taking photos.
According to the article, Iron Gwazi is supposedly "North America’s tallest and the fastest and steepest hybrid coaster in the world. Iron Gwazi takes thrills to new heights, plunging riders from a 206 foot-tall peak into a 91-degree drop and reaching top speeds of 76 miles per hour. Riders on Iron Gwazi will experience a dozen airtime moments, including three inversions, as they sink their teeth into crocodile-inspired thrills.”
[The first sentence of that description is a doozy!]
For a coaster at that level of intensity, the park should have everyone clear their pockets, enforced w/metal detectors and free lockers, like Universal does.
I despise flash photos on rides, but...I can make a small allowance for limited photos/videos on some rides, especially late at night when the parks are very empty. If you are on pirates, and nobody is in the boat to see you using your camera, have at it.
