The CR-10 is now OSHWA certified and the source code has been published on Github. :D
This is mainly down to the open source advocacy, in China, of Naomi Wu. (@realsexycyborg (https://twitter.com/RealSexyCyborg))
She has released a video on it.

While the CR10 is an older printer it is important that the source code is available for several reasons, the main one being that it is part of the GPL terms. Another reason is that it allows for much easier modding of the printers which should allow them to be upgraded into the future.
