I wonder how much the reason they are landing on Linux is that there are multiple companies actively trying to pitch Linux to existing Windows users.<p>RH for instance seems to be heavily pitching RHEL (never mind Fedora and CentOS) towards corporate and the Military-Industrial complex. The latter in particular are interested in RHEL after some poor experience using Windows on warships and similar.<p>But at the same time there is a pile of MSCEs running around in these organizations, and so there is a incentive to make daily Linux management at least superficially similar to reduce retraining costs.
