Excerpt from Gates' Testimony in the Antitrust case...
"433. In addition to requiring Microsoft to auction off its Office technology to three bidders, Section 14 would require Microsoft to continue to invest, for ten years, in developing new versions of Office for the Apple's Mac OS, with "features consistent with Microsoft Office for Windows." Section 14 would obligate Microsoft to invest its resources in this way without regard to the economic or technical viability of doing so. 434. For example, if the Apple Macintosh platform were to lose share in the futurea possibility that cannot be ruled out given Apple's "near death" experience in
the mid-1990sit would be economically inefficient for Microsoft to continue to invest in building applications for the platform. Other changes in business circumstances, such as a decision by Apple to focus on customer segments that generate little demand
for business productivity software, might also render it economically unviable to continue to build new versions of Office for the Mac. A lot can happen over ten years."
