Though the petition is about Germany, in the US some entitlement programs come with work requirements that can be satisfied by volunteer work. Given the tech job market and how the US government's labor policies are detrimental to native workers, allowing them to keep their skills sharp through open source work while also satisfying the work requirements of various social programs, it seems like a decent trade-off. This presumes the government and the donors to the politicians that run it don't really want native workers to be unskilled. Their actions indicate the opposite, so that throws a bit of a wrench into things.
