I think what we'd all like to see a world where there is more competition in the tech market. Unfortunately for MS they became the dominant player in many markets and (like any company in that position) stagnated, procrastinated and behaved in a protectionist manor. Note that this doesn't reflect on anyone within MS, large companies behave in ways individuals can't control.

Now, does MS have to die for there to be a more competitive tech market? No, of course not but if MS does die it doesn't really matter. They are not the sole providers of technology.
