I should say the "hoarding" is a relative term. It probably has to be defined in terms of your normal rate of consumption for the amount of shooting you do. If people who never bought components more than a year ahead in the past suddenly start buying two years ahead, that will create extra demand and probably a short term shortage. But if they jump from two years ahead to buying 20 years worth of supplies just to keep rather than use, or if they buy large orders to sell it off at a scalper's premium, then I expect they can be thought of as hoarding without too much fear of contradiction.
