How exactly is Linux becoming popular going to make my EXWM setup suck? To be fair, if it does get a large market share, some company is probably going to take MS's role and make a distro that sucks but many people use. But that shouldn't be an issue to existing users unless they take over something like a major DE and you insist on using that for some reason. For IT people, having the possibility of running a decent shell and sshd in most desktops would be terrific.

You mean other than Ubuntu and the likes?
