This makes sense, but it is a number of powders if "old style" powders then, not just W-231. Interesting. I wonder if Zip will go away, as it is a very close cousin, if not the same thing.
I had the same question in mind and sent the question to the Hodgdon help line. The following is the answer to my question, which appears below the answer. I does seem to confirm that this isn't just an Internet legend. BTW I don't think Zip is a Hodgdon powder or who actually makes it, so it doesn't answer that question.

Right now, it would be more prudent to tell you that there is no intention of discontinuing H110/W296 nor do we intend to discontinue Titegroup or Titewad.
The majority of powders that the plant wishes to discontinue are non-canister products rather than the canister products which are used by the reloading public.

Subject: Win 231 and similar powder
Mr. Daly,
The email below appeared in a post on The Firearms Forum. I assume it is a valid email from you and it leads to a follow on question.
You mention “231 as well as a few other powders.” My primary powder has been HP-38/Win 231 and while I can easily change over (I was already starting to work with Titegroup with good initial results for my purposes) I would like to be sure I don’t change over to one of those “few other powders”. I would also like to know if any of my other current powders, such as H110/Win 296, are also going to be phased out. Could you tell me what those other powders are?
Thank you,
"Winchester 231 certainly has been hard to get. The plant that makes Winchester powders does not want to make 231 as well as a few other powders. These older technology powders have different chemistry than the new powders and this older chemistry makes it much slower to make powder: basically, you can make about 2.5 times as many pounds of new chemistry powder in the time it takes to make 1 pound of old chemistry powder. During the process of making the old powders, the waste stream created is huge compared to the waste stream of the new chemistry powders. Chemical waste is very expensive to get rid of. So, the plant wants to phase out the old chemistry powders and replace them with new chemistry powders. While they are still making 231, the amount is being reduced and the amount of new powder such as Titegroup and Longshot is being increased.
Now, we are kind of stuck in the middle. The market is demanding 231 but the maker is not wanting to produce the powder. The result is, over time, 231 is going to go away. Shooters should begin using other powders as they can.
