I remember reading elsewhere that he accepted that explanation (right in the beginning when the video went viral first) as well. He was recently signed up for some record deal by the man that talent spotted Justin Bieber. Perhaps there was a diktat/mandate from those circles as to to not antagonise the "prospective audience" for his music anymore.

Jackie Chan had similar problems when he made the crossover to Hollywood (Source: his autobiography and Wikipedia entries). So, I won't be surprised if PSY was made to temper his views lately to avoid unnecessary controversy to his new paymasters.
