> We will no longer distribute source code for the entirety of the Solaris operating system in real-time
In the case of Open Solaris, the code never came out from that point onwards. For Android, the likely end goal is to do the bare minimum of distributing only copyleft code that they don't own copyright to. Until those get replaced with a closed alternative.
I'm trying to think of a mobile OS feature addition that has made me say "I need to upgrade my phone" and it just hasn't happened recently. It's more like, damn it, the dastardly thing stopped receiving security updates and now I have to replace it for no good reason.
Isn't Android done yet? What further development is required that couldn't be done by the community?
