This is a really bad sales/marketing mistake on your part. Competitive analysis and comparisons are huge tools for any company looking to learn from their competitors, identify areas opportunity, and distinguish itself. Watch most ads on tv for example and you will see this comparison all the time. Phone companies, cable companies, car companies, restaurants, etc. How many times have you been on a website and seen a table breakdown of product differences as a selling tool? If I'm a sales person for a company, you better believe I am going to learn everything I can about my competitor and use this to my advantage to better sell my products.
Interesting point, WP. I think it was a smart move on their part to take an advertising spot.
