What mojo..?

This may have been before your time, but believe it or not, at one point (late '80s through the '90s) Microsoft was feared. A standard question VCs would ask new software startups was "what is your Redmond Strategy?" -- meaning "what will you do if/when Microsoft decides your market segment is interesting and decides to take it for themselves?"

because a MS monopoly is really really good.

I don't want a Microsoft monopoly to come back -- one of the most liberating things about the Internet as a platform is how it let you skip the need for a Redmond Strategy -- but it would be good for everyone who buys/uses tech to have Microsoft as a healthy competitor on a level playing field. More choices equals more competition equals more innovation.
