Yeah, they clone or buy ideas and are known to beat their competition through illegal practices ... but no other company I know can be so infected with the NIH syndrome and get away with it.
"far more open standards" is really subjective. Microsoft invented Ajax. And before IE 6, when they've stopped caring, IExplorer kicked Netscape's ass.
And to me, standards are also relevant for hardware ... Microsoft is know to favor standards and openness in hardware. That's how they've beat both IBM and Apple.
So in the grander scheme of things, we don't know which company served a greater good. From my perspective computing wouldn't be as ubiquitous as it is today without someone like Microsoft.
