Obivously, and I'd argue rightfully. Microsoft HAS lost market share, especially if you include tablet/smartphone OSs in the mix. I cannot seem to find it now, but not too long ago I ran across a survey which included portable devices into their calculations of OS marketshare percentages, and determined that Microsoft now has a minority share of the global OS market when those numbers are included.

Microsoft still dominates on the desktop, but the desktop doesn't matter like it once did. I doubt that the government will express much interest here, and rightfully so.
