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.
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.
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.
