Brewing these days is uniquely local. When buying craft, you're buying not only good beer, but you're supporting your neighbors and fellow enthusiasts in the craft. When a beer gets bought by the big conglomerates, the feeling of supporting "the little guy" goes away.

I know multiple people who stopped buying Karbach beers after they got bought. Sure they'll drink it if it's free, but why support bean counters and 1%ers when you can give some money to the people doing it for love?
