SERVERS!! Its about the servers!!
I have seen many deep insights as comments. All, it's about the servers... If there is any place where Linux has a fat chance of becoming a top 3 finalist, it's on the server side.
Around me, I see more and more companies seriously looking at Linux on z/OS, not just a few, but hundreds of servers. The new IBM zBX box that runs Linux as well offer great alternatives for expensive Unix servers and Windows servers. Serious companies do this, only to see that the Linux community seems more interested in the fact that Mint is a better Gnome is a better Ubuntu.
Stop. Please. We want the industry to take us seriously, so we have to focus at the things Linux is recognized for, not for what a lot of people WANT it to be...
