Where'd you hear this one? I've been following the derpy debacle over the last week, but i never found anything to indicate hasbro itself was backpedalling on the issue. From what I've gathered so far, apple threw a fit over the episode where she is referred to by name and removed it from iTunes. Around the same time time WeLoveFine (the license holder for MLP merchandise aimed at adults, and maker of many awesome things for Bronies) removed the name Derpy from any item names or descriptions. There were also a few petitions floating around claiming the name was Ableist and offensive to the mentally handicapped.
On the other hoof as it were, The Hub never removed the episode stream from their website, and in fact featured the episode unaltered on it's front page. WeLoveFine also never removed a t-shirt they had that actually had Derpy printed on it, and not only returned most of the derpy references to the site but added a new one with a picture of Derpy underneath the word "Misunderstood." One of the voice actors redacted the word Derpy from her blog, in a manner that was widely taken to be a passive aggressive statement of her opposition of a change. Lastly, the screenshot below showed up a few days ago, supposedly as a response from Hasbro UK to the derpy rumor milling.

I've yet to see anything about an official statement from Hasbro US though. All the info so far has been subject to interpretation, there's been very little in the way of official word. So pretty much, designed to send an internet based fandom into a rumor-milling death spiral.
