CC-BY does not limit use at all. And we felt we needed this very open copyright license to deliver all the freedoms that the FOSS ecosystem expects. At the same time, we felt that we should try to avoid fragmenting the data and the resulting confusion as to its source and quality. We can’t restrict how someone can use the data, without creating a conflict with CC-BY, nor do we want to. But we can control what someone using our site and API may do.
