Who care about the audio codec used when it won't be the original versions of the movies. That should be the reason to boycott the release, although Matthew Wood doing the sound design means it will be pretty awful anyways, regardless of DTS or Dolby. He remixed star wars in 5.1 on the 2004 dvd and it was shit. So bad that a fan had to sync the 1997 laserdisc ac3 to the DVD,lol.

So who was responsible for the Audio since the first 85 remix?

Like the music editor, the mix supervisor. Burtt is the sound fx guy.
