I don't think most people have any understanding of what a DJ does anyway, so I can't see this game making a bad name for the masters. I've spent years explaining to people that, "No, I don't do weddings, I'm not that type of DJ. No, I don't have a radio or podcast show. NO, I certainly DO NOT play Britney Spears or Black Eyed Peas. GODDAMMIT! ARE YOU EVEN LISTENING TO ME?"
I think there is a very limited number people who really understand the craft, whether it be a set with hours of perfect transitions or straight up turntablism. They have no idea how much work is involved with the technical aspects, maintaining the energy of the crowd while retaining your integrity as an artist, and the inconvenience of dealing with the drunk or drugged up patrons that think you are there to talk with them. In fact, most people don't even consider DJs as artists, which is the really fucked up part because they have no idea.
Sure, a lot of noobs will think this will make them DJs, but as you said, a lot of them already think that way without the game. As I've said, people don't really get what we're doing anyway, so it doesn't affect me. Besides, playing guitar hero doesn't make people think they are a guitarist, so hopefully common sense will prevail with the masses regarding DJ Hero. (Okay, well, maybe it won't...)
I'm looking forward to a fun game that involves something I am interested in, and I'll probably be good at it. I'm not worried about the misconceptions of others. These are the same ignorants that think all electronic music sounds like "Darude/Sandstorm", the same idiots that think a remix of 50 Cent makes a dancefloor, and the same dinks that don't understand that, like any other craft, the tools you use can help make a difference. The knucklehaeds that think DJs are just jukeboxes are the only ones that are going to run their mouths, so just ignore them.
In my mind, it's just a game, and chumps are chumps wheather they play this or Halo. Besides, who knows how many kids that might typically gravitate to the Jonas Brothers will play this game, be blown away, and grow up to start another mainstream electronic music revolution like the one from mid-90's?
