Anti-brand Idea

So much energy is devoted to branding yet so many brands are annoying and have strong weaknesses. Brand Hitmen would be a services company that is hired by companies to target these weaknesses in their competitors. Any number of actions could be taken to erode the brand of the target company including publicly poking fun at its name, leading a negative PR campaign against the quality of the brand, turning the brand name into a synonym for poor quality/something gross/etc., doing things to make the brand cheap/trendy/etc., and so on. An example would be making negative connections between the similar sounds of IP phone company "Vonage", and the word "Bondage" such that every time consumers hear the company name Vonage they think of S&M sex, building (for most people) a negative connotation. Viral marketing tactics would be used for them most part. Everything would be legal, and the focus would be on de-branding rather than corporate defamation, like drawing attention to the fact that the company uses sweatshops for example. The focus instead would specifically be on using the target company's own marketing message against them.
