The project didn't fail, it was on pace to succeed, which made Microsoft swoop in and basically bribe them to switch back.
The lesson being, switch to Linux. Either you'll switch and save money, or Microsoft will bribe you not to and you'll save money.
> Linux in Munich: 'No compelling technical reason to return to Windows,' says city's IT chief

The reason was probably a shift in IT management who wanted to keep things "simple" with some vague thing about keeping one platform since they had kept previous windows machines around which were apparently "absolutely needed". It takes heart in the management to keep Linux around, which isn't always a reliable thing. Even when there was no "technical" need to use the more expensive Windows option.
But this sounds 100% like a Microsoft sales/marketing job, which they are amazing at. They've really perfected selling to big firms, which you could see with the growth of Azure. Which I witnessed when they unleashed their sales machine on startups to get them to use it, and it was quite interesting to see in action.
Taxes. Politicians still think Microsoft pays taxes. Though 60M [1] per year in taxes while paying much more for their software is technically a retarded thing to do deal-wise.

It only makes sense to take the bribe in that case. It always makes sense to prepare for the switch, because if they won't bribe you enough to stop then you can always actually do the switch, which is still better than the status quo.
