Of course, as a shareholder it probably wouldn't be. Microsoft will challenge these restriction before challenging the decision generally. Aside from the fears about a change in President and what it may bring, the Justice Department and Judge Jackson have set a quick appeals timetable to avoid big changes. The decision in the consent decree was only restricted to the decree. I think this will be a difficult and precedent setting case.
Ideologies are important in such cases.
The Chicago School of economic theory will be tested as to what constitutes abuse of monopoly position. However, as can be seen in Judge Jackson's assessment and many commentators there are many people who believe Microsoft handled this case very poorly. Indeed, this has been a major problem for Microsoft in this matter for years. However, Republicans have been among the strongest supporters of the antitrust laws. I do not think they will be weakened.
