Earlier quoted context omitted.
Not true. Microsoft built a huge local branch there and as a result they've moved back into the dark abyss that is proprietary, non-free software.
That is the conspiracy theory that some are telling themselves: that this is THE reason why Munich moved away. AS IF! Here's something more likely: Munich was ready to move back because the project was expensive to maintain, cumbersome in practice, killed productivity and was generally unpopular with the end-users, and Microsoft's new branch was just a cherry on top.
You might not like this line of argument, but it's not a "conspiracy theory" since it's well-supported. It's disingenuous to completely dismiss the role of political influence on a government decision.
