A late response, but the legal action was threatening to sue me for infringement of their intellectual property because my portfolio included projects I worked on there. It was an obvious case of Fair Use, but like the other guy said, suing me would have been pocket change for my employer and devastating for me regardless of who won. So I took down my portfolio.
