The thing about computer security flaws is that unless someone makes a point of publicly exploiting them, others will go around quietly exploiting them. It is almost certain that someone was quietly siphoning Jonathan's card. Would all the donors really prefer to have their donations be embezzled like they are at a skeezy charity front like Palotta or Komen? Why, just for smug satisfaction of feeling good about giving, without any concern or accountability regarding whether the gift is doing the good you give yourself credit for?
There is no use in condemning Odio unless you have a plan to fix the security hole he highlighted. Otherwise you are going to shutdown the open and honest takers and willfully ignore the quiet and dishonest takers.
Being able to mark a card as "only purchases @foodstuff products", or being able to blacklist it from refilling gift cards would be the easiest way to close this particular hole.
If you could only purchase actual physical objects (ideally, only fresh food, rather than, say, a coffee-maker), that would go a long way toward preventing misuse.
