That is a reasonable possibility, however, my dilemma is after 20 years of my steadily buying the stuff for my machine why all of a sudden the shelves are cleared out. I have never seen that before except with an upcoming hurricane or a quarter inch of snow, both apparently being equal in disaster status. I guess it will remain a mystery except in speculation. Not the worlds biggest problem.
That direction to clean it after every use would cause me to not use it too. Knock on wood, but, I have been using my C-pap for over 20 years. Every time I have gotten new ones (they do break down) I get a two hour class on how to use it and part of that lecture is "it must be cleaned everyday". I just keep quiet and nod my head, because I never clean mine and in spite of all those new TV commercials that have lines of people telling you how sick they got because they "missed" a few days cleaning it and now have infections that would scare Dr. Salk. Maybe, I have an overactive immune system or something, but, whatever it is I'm fine with it.
