FWIW, there are now actually very few selfie sticks in the parks. In my last two visits, I didn't notice any actually (though I wasn't looking for them either). It was only at Disney Springs that I saw any being used, so if people are still sneaking them into the parks it wasn't to the point where they were annoying or even grabbed my attention.
I think back to the days before Disney announced the ban, during a visit to a park. The sticks were absolutely everywhere, bumping into people, blocking walking paths. The last straw in my patience was on the Haunted Mansion when a stick appeared around the corner of my doom buggy, then over the top, to catch a sweeping aerial view of the ride. It was absolutely awful.
