Its interesting that a winery would need to talk about other producers products instead of focusing on their own juice..... unless of course they think that their stuff doesn't stand its ground....????
As for Malbec made outside Argentina, I have somewhat limited exposure to "French Malbec" and have only tasted a handful of California Malbecs. In my experience, the only region outside of Argentina where Ive found Malbec that made my bells ring was in South Africa. I am of course (very) biased on all things Malbec, but I would venture to guess that Australia must also have some good Malbec made somewhere.... and also California must be doing it right - its just a matter of finding the right producer.
Having said all this.... you know where to go if you want the "real thing".... LOL
