Good point. Here are the constraints: > No exchange of payment. The Wikimedia Foundation does not pay carriers to zero-rate access to the Wikimedia sites and does not receive payments from carriers through Wikipedia Zero. > Wikipedia Zero cannot be sold as part of a bundle. Access to the Wikimedia sites through Wikipedia Zero cannot be sold through limited service bundles. > No exclusive rights. We try to partner with as many carriers as possible to maximize the number of users that can benefit from the initiative. > Open to collaborating with other public interest sites. Our main goal is to promote free access to knowledge and we want to help other similar services interested in doing the same.
