The city administration of Munich switched to Linux, migrated all data and users, trained them etc. for millions of Euros, and then eventually switched back some years later since staff productivity was way down, and users didn't feel comfortable in the OS environment.
You can't enforce a change. Linux is great, especially so for tech enthusiasts, but the average (or probably below average) user might have a hard time to adjust.
And when performance is measured in workforce efficiency, then you have to accept that it's simply not suited for every environment.
