Well the economic theory (as far as I can recall) is that even in a fiercely competetive market, so long as there is no market failure, there exists an underlying impetus to agree on standards (or rather adopt a single one, from the scariest player). The game-theoretic (!) motivation is to increase network externalities overall, hence growing the size of the market as a whole and giving everyone a simlar percentage slice but of a bigger cake. I think its happened enough, in web standards, communication standards, etc, that it has some merit, but as far as a monopoly is concerned such agreement is anathema. They'd quite sensibly rather tie everyone into their own dedicated systems using such useful things as er...say... activex, subtly different css models and silverlight... ;) 'Course its a long time since I was an economist, and given economic theory is about as scientific as the fashion industry, the above may all now be viewed as bobbins.
