The BA's selling point is "local and independent is better".. better how? Better for the economy, better business practices, better for your community etc etc. Over time most people will turn that into "better quality" or "tastes better". Is the BA trying to intentionally mislead people? No, I don't think so, but they are certainly taking advantage of how human emotions work to push their message. In essence that's how all advertising works. Is it meant as a quality statement? No, but in 5 years that's not what people will remember about it. People automatically assume "better quality" and pay a premium for things like "Natural", "No Corn Syrup", "Free Range", "Dolphin Safe" "GMO Free" etc etc, all of which are unregulated and mostly meaningless statements (Organic is the only one certified by the government) and don't always (or sometimes ever) equate to product quality. It's a shell game.. and it always has been.
While I respect your profession as a food scientist and I agree with the "Angus Beef" argument (*to a point) you are only looking at this from one side of the coin and here is exactly why you are wrong: Big Beer is trying to make itself look like Craft. Even Wal Mart has gotten into the act making a beer brand that tricks the consumer into thinking they are drinking a craft beer and not clearly making a delineation that the beer is actually contract brewed by Wal Mart (for instance, Costco Does contract brews as well but it's under the "Kirkland" brand).
So, what you are basically saying is: you would prefer big money and big corporations to keep the consumer in the dark and you are fine with people being lead along like sheep with advertising, but a piece of information that lets people know they are drinking from a struggling independent brewery is a sham?
In the end, it's up to the consumer to educate themselves. There is no indication of quality by the BA logo but it does give you a piece of information that is valuable to both the consumer AND the business. It gives CRAFT breweries a way to separate themselves from "CRAFTY" brewing and big beer marketing.
*And, FTR, the difference between the "Angus Beef" label and the "BA" label is that the "Angus Beef" label is open to anyone whno buys Angus Beef. McDonald's has an Angus Beef burger. If McDonalds started opening up little hole-in-the wall BBQ places around the corner from your house, wouldn't you like to know? I sure would.
