This would seem, at least by first impression, to be as clear an example of artificial linguistic in-group snobbery as we could ask for. People who favor vinyl records are a self-defined in-group to begin with, and here we have a fake linguistic rule to further establish who is in and (more importantly) who is out. I wonder if its precise origin can be established. Also, what will they invent next, should plural "vinyl" actually catch on to the extent that it no longer serves its purpose.
