I don't see why these types of articles have to focus on the notion of a 'victory' for either side. Microsoft isn't winning, but it's making a lot of money in various areas, so it's not losing either.
Microsoft probably is concerned about declining market share, but to suggest it was always targeting 100% of the market is misleading (there are people that have always and will always run Linux, and there are other people -- particularly large enterprises -- that they are much more focused on).
