Actually, it was about courts deciding the liability scope was too wide and could harm innovation, as per your linked source. "Although the D.C. Circuit found that it was possible to examine high-tech industries with traditional antitrust analysis, the court announced a new and permissive liability rule that repudiated the Supreme Court’s dominant rule of per se illegality for tie-ins, due to the court’s concern for the dynamic effects that a per se rule would have on innovation." Ergo, the tie-ins were found to have happened by point of fact but not found to be illegal by re-interpretation by the courts of the illegality of tie-ins. The Justice Department then reached a settlement (the win on their side being that they wouldn't have wasted the years of prosecution). This goes a way towards explaining why there hasn't been a similar Microsoft-scale antitrust case since the Microsoft case in the US.
