[3rd3]

The "lesson" does not seem so clear according to the article you have linked:

> Schneider claimed that the decision had been political, “not made on the basis of facts”

> “We do not see any compelling technical reasons for a change to Windows and Microsoft Office… We solve compatibility and interoperability problems by providing MS Office, mostly virtualised, at workplaces that need to work together with external offices on office documents.”

One point of critique was the difficulty involved with 3rd party programs on the Linux laptops. But with MS Teams, Zoom etc. running in the browser and/or having actual Linux clients these days, this may be much more feasible today.

The opposition claimed the decision to abandon Linux was a purely political one. The mayor who pushed the return to Microsoft, Dieter Reiter (SPD), was a known Microsoft fanboy, but he (of course) denied personal investment in the reversal.
