Until you can bribe officials to the tune of billions the quality of your software won't matter. The only reason why ms keeps winning is that it keeps bribing.
MS also keeps winning because they have billions of dollars to pour into the UX of their Office suite. The FOSS community doesn't spend a lot of money on hiring professional UI designers, and it's "do-ocracy" doesn't handle UI design well because UI design isn't seen as "doing" so much as nitpicking the choices of the programmers who are "doing all the work".
MS bribery is a factor, but if we use it as an excuse to ignore our own faults as a community then we're just screwing ourselves over.
