He is a douche, and I'm a knee-jerk copyleft guy. But my favorite douchiness indicator is not the plagiarism, but all that hilarious "pressing charges" with Facebook stuff. Here come the Facebook police!
Aside from the Simmonses, though, the "I don't get that I'm plagiarizing" thing is utter bullshit. What that NYT article misses is that deliberate pastiche like David Shields' new book, or that Jonathan Lethem article in Harper's, or Negativland albums, or Chuck Mee's plays, or even the work of DJ Spooky (who is kind of a charlatan) or Girl Talk (who doesn't really hold up to more than one listen, IMO) always acknowledges its sources. Whether one likes that sort of thing or not (and I don't always), the people who make it actually expend effort and use aesthetic judgment, etc., just like any other artist. Lumping that kind of thing in with opportunistic scam artists trying to pass others' work off as their own does a disservice to real, legitimate arguments for copyright reform.
Not to mention that the piece smacks of stupid Generation Y hysteria, like the articles that say kids today need constant praise in the workplace, or are always sexting and having rainbow parties, or whatever. Young people aren't morons, or at least they're no more moronic than their elders. Having an iPhone doesn't make you suddenly forget what plagiarism is.
