Slide 6 lists staff, including S Jobs and S Wozniak. That leads me to believe it is Apple, though I have no idea if they were involved in other companies.
I think that mention of Apple was simply missed by whoever redacting the document. They're saying "Manufacturers like us have already started to offer assembled computers, disrupting the dominant marketshare of unassmbled kits."
But I admire your quest to find who the real company is.
