The concept of "fair use" applies to copyright law, but it doesn't apply to trademark law at all. And if GetSatisfaction doesn't have anyone on staff who knows the difference between copyright law and trademark law, while they are copying business corporation trademarks to display on their site, they are acting in a seriously unprofessional and legally dangerous manner. The lesson for employees of GetSatisfaction would be to not accept stock options as compensation, and to start sending around resumes to a company that is more legally prudent in its business model.
Anyway, that's not the point.
