"Slowly, behind the scenes, Microsoft continues to try to portray Linux as risky and Microsoft's patent coverage as insurance. Given that the company selling the insurance is also the one threatening a lawsuit, however, Microsoft needs to step very carefully to avoid the "extortionist" label. I personally believe that it has already crossed the line and needs to get back to competition between products, not lawyers. Microsoft Windows competes well against Linux. The company doesn't need patent trickery. It has a compelling, valuable ecosystem that it can use against Linux. Why does it continue these Linux kidney punches, of which Microsoft claims it has closed more than 500 deals?"
