Being bought up by a corporation isn't necessarily bad... until the corporate cost cutters show up.
I had the unfortunate experience of spending the last few years of my career at a company that could no longer grow revenues. So the only way to meet profit growth targets was cost cutting. Now, there is nothing wrong with cutting out truly unnecessary costs, but just doing that requires careful analysis, and is a lot of work. It usually gets implemented as "cut X% across the board," without regard to consequences. In a brewery, that eventually leads to using lower quality (cheaper) ingredients, and short cutting processes, leading to inferior results. We can only hope that BP avoids this fate.
