Now they push projects like OpenDesk[1] to fully replace MS Office (365) and OpenCode[2] where they open-source all software that is build with public money.
In my view, this has led to the German economy having more confidence in open source, and that open source can be used and maintained as a model for software over a period of 5-10 or even more years. Instead of buying licences and hoping that the manufacturers will maintain the software for at least 5 years and provide updates. In addition, there is the realisation, not least as a result of the change in the law and the current global political situation, that sovereignty is a very important factor.
