The license has to be central to something like this, and it has got to be copyleft and/or even some sort of nationalist German-MIT license that only grants permission to German citizens and companies. You can't let the German taxpayer get exploited for the benefit of foreign corporations.

The "spirit of open source" is not real. If you think that the only real gift is MIT-style permissively licensed stuff, you should be proud not to be recognized by the government. You should ask for no credit and no reward. Christmas gifts you buy for someone are taxed, and are not considered charitable contributions.

Otherwise, it is a great and vital idea. "Open source" is just not specific enough. It may even exclude GPL.
