No, they would not be able to say that.
And be sure of one thing: independent manufacturers (i.e. those not bound to broadcasters/providers) are benefiting greatly from the existance of an active hobby community, stimulating interest in satellite TV as well as generating sales.
If I recall, the Digiquest P2000 incorporates 2 embedded CAMs - Viaccess AND Mediaguard. So if they were to raise questions about your cards, you might like to ask them why they include those CAMs for the UK market, since neither of them are used by the UK satellite broadcasters, and official subsciption cards can not legally be obtained in the UK (unless you count the mature content subscriptions such as SCT - itself of dubious legality in nanny-state Britain...)
