I'm French and I live in France. Here, most of our truffles are real truffle.
We do get some Tuber aestivum as well, but that's alright because they're displayed as "truffe d'été". No harm done.
As the article said, the "truffle flavour" has nothing to do with the real stuff, and outside of France, Italy and Spain, you probably won't get them on the market. You might be lucky in some restaurants all over Europe. But everywhere else it's propably not the "real" black truffle. Especially, if they put some in ketchup...
