Summary: An "Unknown" OS (not Windows) is taking market share away from Windows; whatever is going on with these statistics, it seems clear Microsoft isn't coping with a fast-changing world, hence so many layoffs (far more than 10,000 -- the "official" number that media loves parroting without investigating; Microsoft is 42 billion dollars in debt and the debt grew more than tenfold since 2010)

"Microsoft, the world’s most valuable company, declared a profit of $4.5 billion in 1998; when the cost of options awarded that year, plus the change in the value of outstanding options, is deducted, the firm made a loss of $18 billion, according to Smithers."
