I'm the sure the same is true of "Miller" - put Stone IPA into a Miller bottle and people who love Stone will hate it. Put Miller Lite into a Leinenkugel's bottle and the negative reaction goes away. It's just one way that large companies make money off of people that hate large corporations. See also: Chipotle vis-a-vis McDonald's.
It also presents an interesting dilemma. What's the difference between Leinie's owned by Miller and Leinie's NOT owned by Miller? Do these corporate associations really make a difference? If Starbucks makes good coffee, hires local people to run their coffee shops, and generally act as good citizens in their communities, why do we care if there are over a million stores and the coffee comes in a white cup from a green be-smocked barista?
On the other hand, we have to recognize that at such a grand, corporeal, corporate level the business is not about the customer, except to the extent that it helps to separate said customer from customer's dollar bills or add a tally on the minus side of said customer's bank account. The feeling is that Starbucks doesn't care about creating good coffee or even a good coffee experience; rather Starbucks is an expert at making the customer THINK they are getting good coffee and a good coffee experience while providing that thought for as little money as humanly possible. Miller wants you to THINK that you are getting handcrafted, artisan beer from Dick and Jake Leinenkugel even while making much of the product at a faceless facility in Milwaukee by people who probably don't even know that the product going through the tubes will end up in a Leinie's bottle.
But, if it's good beer ("good" being defined as: "you like it") who cares where or by whom it is made? How deceived do you feel knowing that the vast majority of Guinness, owned by spirits giant Diageo, is not made in Ireland - and to qualify as "imported" it's simply made in Canada and crosses our Northern border? Does it bother you to know that Blue Moon, a slice of orange heaven to many people, is owned by Coors? Would you continue drink and exalt Matilda if you knew that Goose Island and Anheuser-Busch have been in bed together for years?
And how is any of this different from Sam Adams? Sam Adams is the largest "independent" brewery in the United States.
Of course, all of these make a mockery of the "local" product that many claim to be. Sam Adams is about as "Bostonian" as cream pie. Guinness is about as Irish as most of the revelers packing Claddagh on St. Patrick's Day. Leinenkugel's has as much to do with the Northwoods as the Chicago tourists who lord over the servant class there.
At the end of the day, to me at least, the question is: what do you like about drinking beer?
Are you merely looking for beer that you like? If so, then who cares where it's made? But, if you are looking for a producer that cares about their product, if you are looking for an artisan that wants their consumers to be enlightened, if you care about your dollars being spent on local products, if you value transparency and artistry over quantity and status, then a heavy weight is put against these marketing companies merely passing off the same old industrial lite beer as something new and exciting simply because they put lemon-syrup in it and call it "Leinenkugel's Summer Shandy."
