> This is the problem with getting tech news only from HN.
Most of us have worked one or more tech jobs, and HN isn't the source for the assumption that nobody uses Windows as servers. That nobody is far fetched - of course .net shops will most probably be deploying on Windows; for some reasons most of the Java shop do so as well.
But outside that, Linux or BSD is the favored deployment platform. And the OP's argument basically boils down to server vendors can't afford to not boot Linux, not when Linux has a significant market share.
