It seems Hasbro has become, as Gilda would say, "flip-flops".
The Last Roundup was re-added to iTunes, but it is different from the original. They changed Derpy. In fact, here are the changes...
1) Her eyes are not so misaligned.
2) Rainbow Dash doesn't call her by name now (meaning she not referred as "Derpy")
3) Her voice was changed.
I'm appalled that they did this, which was done by order of Hasbro because there were complaints that Derpy was "offensive". She is as offensive as any other character on the show. People offended by Derpy, and not by a character named after an alcoholic beverage? Seriously. The voice change wasn't too bad (but it doesn't have the feel the original had), but they messed with the eyes and took back the name. She was just fine the way she was, and added an aspect to the poniverse that not everyone is the same, but are accepted nonetheless. This is not the worst of it. This change could very well affect the episodes to come because Hasbro is so easily swayed by the minority to go so far as to force such changes that aren't even a problem to the populous as a whole.
One last thing before I stop ranting, which will come direct from the show itself.
Dear Princess Celestia,
My friends and I all learned an important lesson this week: Never judge a book by its cover. Someone may look unusual or funny or scary, but you have to look past that and learn who they are inside. Real friends don't care what your cover is. It's the contents of the pony that count. And a good friend, like a good book, is something that will last forever.
Your faithful student,
- Twilight Sparkle
- My Little Pony: Friendship is Magic, Season 1, Episode 9 - "Bridle Gossip"
So, like I said.....
Flip.
Flops.
