The way it was explained to me has to do with adding an RasPi to a commercial product for sale. Seems it is a legal thing. Most of those make no logical sense to me. But I would think if I came up with a product called a COMPUTE MODULE that you would want people to use it in their commercial product.
Also it does come down to one person maintaining and coding the outernet project. Add a different core, double your workload per patch. Yes, I know that GIT can post those to both pushes at the same time, but let's just say for the price you would not get much better service.
Ever have a Compuserve account? Imagine you got that for free after buying a 300 baud modem. From a Satellite.
Oops, forgot to mention one thing. The whole team are packing up Kickstarter packages for the people that initially paid for all this free stuff we are getting to download.
