Most fortunately, there have not been any casualties-- the injuries suffered by firefighters were "minor" according to CNN.
"Fortunately, nothing irreplaceable was lost," [Ron Meyer, chief operating officer of Universal Studios] said. "The video library was affected and damaged, but our main vault of our motion picture negatives was not."

Will the "No no" studios wait till all their video & audio archives have rotted or have been destroyed to lament not having preserved them in some way?
(Whether by licencing out the major scores, releasing them themselves, or at least making backup copies of evertyhing and keeping them in secure locations.)
Whatever the costs, they would be much much less than a loss of everything-- thousands of movies and scores they could no longer profit from through various releases and anniversary re-releases.
