Personally I would not have seen a swastika here, but when looking for it, here it would be more obvious, the python logo has only half of it.

Still, questionable if it was intentional .. and if it was, does not necesarrily mean they are Nazis (they did not invent, but just used the old symbol).

Also this project was funded in part by the german Federal Ministry of Research, Technology and Space and they are not known to fund open Nazis in general.
