I’ll admit to perhaps being a bit overly fond of Derpy Hooves heck, I have a picture of Equestria’s Clumsiest Pony at the office so I’m not particularly happy to hear that the newly-arrived downloadable ($2.99) iTunes version of “The Last Roundup,” the episode of MLP:FIM that gave her both her name and her admission to MLP canon, has been edited after the fact, and oafishly at that: partially correcting her, um, “vision issue,” replacing her voice with something a bit more generic-sounding, and redubbing the line in which Rainbow Dash addresses her so that her name is never mentioned.
Consensus seems to be that this is Hasbro-originated malfeasance. I’m not so sure: when I think high-handed interference, I tend to think Apple, and the fact that existing copies of the DVD on which this episode is included contain the original cartoon as first shown on the Hub would seem to support this notion. But it doesn’t really matter who did it; it was definitely done. And if you ask me, it’s like reediting The Honeymooners to put Ed Norton in a desk job, lest someone be upset by the idea of sewer workers in this day and age.
