I believe focusing on potential technical problems is the wrong approach.
What you have to look at is lock-in or no lock-in. Any responsible IT Manager should avoid lock-ins / silos as far as possible. This then allows to standardise and use multiple suppliers and much lower TCO.
Without having looked into details (but with some knowledge of the Munich IT environment), I'm sure that most of these technical issues stem from the previous lock-in situation with MS.
There are other solutions without migrating the desktops back to MS / upgrading to MS Win 10 - you could for example virtualise the apps with issues (Standard approach & working very well in large environments). But then Munich could not be locked back into the MS Stacks so easily.
And MS and Oracle are very good with locking their customers in and collecting vast amounts for that.
BTW - I've seen large government environments in the UK with completely virtualised application delivery / desktops to enable staff to work from home, BYOD, hot-desking etc while at the same time securing the organisation's data e.a
At that point which desktop OS you are using has only limited importance.
