These posts evidence a lot of emotion and less common business sense. First, growth in the homebrew market (i.e., selling of equipment and supplies to homebrewers) has more or less leveled out. Consolidation is occurring not only among equipment and supply distributors, but also among ingredient makers. You'd be surprised to find out how much of your grains, hops and various adjuncts are really made and then distributed at the wholesale level by so few players, many corporate owned. How many of your sacred low-cost kettles are really made in one, maybe two Chinese factories, with different labels slapped on. Second, most of the innovation in "toys" has pretty much leveled off. You can achieve a boil, transfer your liquids, saturate wort with hops, etc. only in so many different ways. And you can only buy so many of these toys before you realize you need to brew beer. It's called market saturation. Think of it as we've reached the end of the 60 minute hop boil, and the market is ready to cool down for yeast addition. (Don't forget the American-made wort chiller).
So what's an owner to do when growth isn't there and someone comes along with deep pockets and [Marlo Brando speech] makes you an offer you can't refuse? It's the time-honored conservative American tradition: sell and move into your gated Florida community. In truth, the industry changes with time, as do consumer needs and market demands. (Don't forget other factors such as interest rates, capital expenditures, health costs, etc.). InBev and the other beer-making behemoths are not stupid, and they may be making the rational medium-range decision in trying to figure out small to medium size market changes and how to make money out of it. It's what their investors and shareholders demand of their company in order to stay relevant.
The good news is that there is still a lot of competition and alternative vendors to choose from (e.g., Adventures in Homebrewing, More Beer, etc.), but there's change in the industry. Owners get old, have kids to put through school, and wish to retire. Perhaps LD Carlson, which is a large wholesale distributor, will begin to move into the retail or direct sales market. So, after you all have cooled down, had a beer, you'll realize you'll still be able to buy your made-in-china toys and your grain and hops from the usual sources.
