Where are all these Truffles from?

So truffles are expensive right? White truffles, the Piemontese type, are really expensive. THe word on the street about the whites is that they're pushing 3,000 euro a kilo due to this years scarcity. That instantly pushes them out of the reasonable realm for a small restaurant. Even given the scarcity the quality is supposed to be sub par as well. However places are still pimping the fact that they have these Piemontese white truffles. Are they bolstering meager shavings with the chemically enhanced, yet still somehow accepted, 'truffle' oil? are they using Serbian truffles and pimping them as Alba? Will the madness of using Truffles in absurd applications ever stop?
Apparently in addition to the horrible year climatically there is an ever increasing cadre of inexperienced trufolau, truffle hunters, damaging the fragile ecosystem.
