I love to see these threads pop up and spread the word. I feel we should all do our part and shop with our dollars. To dismiss what we do as consumers as not relevant to what happens in business, is to abdicate any say you have in how the world of business works.
Even after a few years nobody seems to know what AbInbev is up to. That in itself should concern us all. As someone said above, they don't do things like this without a plan. And if you are wondering "what's the harm?", consider the story of what happened in the Minneapolis/St. Paul area where NB is headquartered.
NB and Midwest supplies started well before my homebrewing started. By the time I hit the scene they had merged into one company. They were good, no doubt. They were so good that our metro area of over 3 million people had only one other viable homebrew store in business. (Brew and Grow). There were a few others on the periphery when I started, all gone now because of NB/Midwest dominance in our market. This left us vulnerable when they reached a deal with AbInbev. One possible scenario for them is that they spend a few years perfecting the business, and then start buying up or opening LHBS across the country. When they put their $$ to work on that it will push out the little guys. And because of the hypocritical nature of all of us as pointed out by applescrap above, it could happen like Wallmart, HomeDepot, etc. and kill selection, quality, and variety for everyone. Did we not see them do this to beer over the last several decades?
Don't get me wrong, Brew and Grow is a good store, and thankfully they are pretty close to my house, but many in my area have to drive all the way across town and past NB/Midwest to get to the north side. And they can't always keep up with stock. When the takeover first happened NB/Midwest was the only place locally to get White Labs yeas for instance.
I know I can sound a little paranoid, but it became very personal for me due to my allegiance to them before the buyout and the lack of options I have here.
