Martin Taylor, the corporate vice president who led Microsoft's research campaign against Linux before moving on to the MSN division, is no longer with the company, Microsoft confirmed this afternoon.  
The reason is unclear. Microsoft's statement: "We have made the difficult decision to part ways with Martin, but we don't comment on personnel matters. We appreciate Martin's contributions at Microsoft over the past 13 years."  
People are starting to bail out of MS left and right. Draw your own conclusions from that.
