I see the stick as a photographic tool to get a certain type of shot that cannot be achieved in most cases without it. It places the camera in a spot it could not otherwise occupy and therefore creates an image of interest. While PhotoPass is great and I use it there are so many versions of essentially the same shot that it gets monotonous. Tools like sticks, wrist mounts, chest mounts, action cams and such provide us with different ways to capture the moment in a fun, exciting and interesting way.
Looks like Disney is fine with it. They just posted a video on Walt Disney World Facebook page promoting You Tube "Stars" creating videos. Lots of sticks used.
