No flames here. :) I would second that if I thought they felt they were actually being infringed upon. I see the litigious nature of our society in a suspect light though and I think this is an attempt to unfairly claim some of the market.
Society likes winners but seems to hate successful companies. The "fear and loathing" seems to be directly proportional to the level of success.
The litmus test of success in America isn't the profit margin, it is how many other companies would like to sue. Google attained their success by providing more relevant results quicker than any other SE in the industry, and now that success is already being seen as unhealthy. Makes it tough to play the game if people are only happy when you lose...
