My argument is it isn't a parody at all. They reworked the lyric for their product. It's done a lot in advertising ("I'd like to buy the world a coke" vs. "I'd like to teach the world to sing".) It boils down to this: the Beastie Boys song had more worth than an original song they wrote themselves. In addition to the actual song (which is a snappy professional-grade pop tune) they appeared to be trading on the Beastie Boys name in promoting the video. With limited exceptions, if you're using the creating works of others for your commercial benefit, you should pay the artist. Full stop.
