The original link worked just fine for me today.
I thought overall it was great but I do agree that the Williams Oscar clip doesn't feel very affective. His work was relatively unaffected compared to most of the other departments that won that year.
So as a potential skeptical viewer who might be watching this it does nothing to make me sympathetic to the project or the plight of the OUT.
Keeping in mind that the narrative script is finalized, there's a couple of ways I think that segment could be improved.
The first would be to replace Williams with the Oscar acceptance for Visual Effects. The quality of the clip isn't that great but their work was the most hard hit by the SE.
The second would be to create a quick montage of all of their wins. Which could go something like this:
"And the winner is...[quickly cut between the different presenters saying "Star Wars"]
Or:
And the winner for: [cut in quick succession to the award name (Film Editing, Sound, etc.] is...STAR WARS. *APPLAUSE*
That would help emphasis what an impact the film made on the industry.
Anyway, that's just my two cents. =)
