Yes that is a copy of the trailer. This work did gather a semblance of support, so it still exists in various places. (an ironic one being the old iFilm location which got bought out by Spike TV, so the channel with exclusive rights to the SW films, makes you watch a commercial before watching the RotS 133t Trailer)

In the interview with the creator 133t m4r( he pointed out that this doesn't bother him, the work still gets to be seen, but he was bothered by the sites which burn in their logo onto his piece. Those were some of his concerns.

and he hasn't commented to my heavy lifting of his subs when I put them onto the Celebration live performance of the RotS Trailer.

For me the issues comes up if any video posted online today, eventually becomes commercialized by some organization (as in this case with an ad), why not allow the creators to reap the rewards while they live. and since that seems to be the way the internet is going, then are any of these Cease and Desists done for any reason beside lessening the public support these works have gathered.
