Its hard to accept the author dismissing the threat of bitcoin being banned and then admitting it is difficult to buy bitcoins. If it is difficult to buy bitcoins, its most likely hard to get useable currency from bitcoins. Until you can buy groceries or other real life things in bitcoins, I'd say it is a a very real threat.
Bitmunchies probably pays its suppliers using usual currency.
I'd guess its is just a way to trade money for bitcoins and that they don't really convert those bitcoins to dollars to pay their suppliers. Just a guess.
