That beat Microsoft dead in the server market. In academic and scientific computing. How about the embedded market?
From my perspective the random hobbyists have Microsoft backed into a corner, with only their hold on a narrowing desktop market share remaining.
How many 0-days has Microsoft left hanging open for the better part of a decade while trying to figure out how to defeat open source software?
I think that if Microsoft focused on being the best of something they'd not have a problem right now. I think they focused on being the only of something, trying to make sure no one else could enter the market. I think now they're trying to use money to make themselves an asset in that market.
