From reading the "meat king"'s biography I'd say definitely no.
However, he has a nephew also called Clemens. According to this article http://www.nw-news.de/owl/regionale_wirtschaft/5875170_Fa... the nephew owns 10% of the meat giant, which should be enough to be financially capable to sponsor some open source software. Whether he really is the same guy and whether he really puts meat money into the projects I don't know and I don't want to claim.
