Although we are a big fan and a proponent of the open source movement, unfortunately this project may not free its codebase because of commercial reasons - nonetheless we are committed to make the development as community-driven as possible. Think of this like Bitfinex, for example; no one has access to source code so it's not free software per se, but after all the offered services are good for nothing but the cryptocurrency ecosystem which I believe has now become an indispensible part of the open source movement in general.
