I think the most ethical way to advertise this project is to let it participate just the countries which already allowed the licence for ISP. Otherwise how can they explain it to the investors if they can not get the licence of their country? Just think about it ...
exactly as it will be better to know which country is actually going to support cedris and wisp as from my guess not all countries can support this project and another thing is the project will actually help most rural community but at what cost
