Commies are really, really rare in Germany. I find it personally doubtful that so many are involved in that research area.
Also try to assume that they are acting in good faith.

Open source examples aren't communism, there's no threat of force. It relies on decentralized collaboration and natural willingness to create and share. There's a solid legal framework in place that promotes use, improvement and extension with low cost to all parties.
If you think communism = taking away things from people, I guess you don't know political ideologies that well :)
