Can't get to the video at the moment, but was the comment from Frontalot or Coulton? If it's the case it's likely it was very tongue in cheek, given (particularly in Frontalot's case) they're both probably quite familiar with the OS.

Nope, it was Christopher Tin, who seemed to be trying to make a joke while actually not knowing what it is. Honestly, while his music sounds good, I thought his pitch was quite bland, and the video would have been better with no talking at all, just music and on-screen words.
