...the "mostly by Cubans in exile" is the important part.
As someone who occasionally orders Cuban cigars from the Swiss, I can tell you that they're simply not any better than the same cigar from the same company from their Dominican or Nicaraguan plants. ...especially since the same seeds grew the tobacco. Cigar Aficionado likes to perpetuate the mystique. They benefit from it.
meh... You seem to be arguing that people of Cuban decent do not have magical cuban pixie dust that makes them taste better. Ok... I guess we can agree.
But that's like saying (since you mentioned the Swiss) that you know a Swiss guy living in North Dakota that makes watches just as good as Swiss watches, so clearly Switzerland ain't all that great at watches... But there's certainly a cultural interest in Switzerland of making fine watches, and a long and storied history of them doing so. Are all Swiss watches perfect? Can no other country or ethnic group produce a good watch? The answer to that question is about as dumb as asking it.
There are many fine Cigars made in Cuba. Those that enjoy smoking fine Cigars will be happy that they have a new and interesting place to buy them from. Would they be as excited if we normalized realizations with North Korea and they could finally get those fine North Korean Cigars? No... and that has nothing to do with "hype" and has everything to do with a real and notable difference in the quality of products coming out of those 2 countries.
