I don't like it either, but let's not gloss over the fact that US patent and trademark law is setting up a difficult structure for these guys.
In spite of that, when marketing and lawsuits start taking up significant portions of your time and money that has to come at the expense of other things. I don't think this will do anything to improve the quality of their beer or the morale of the people that choose to get up and come to work there every day. No winners here....
