You might have heard OnePlus has formed a dev team to build its OxygenOS ROM. They even did an AMA on the /r/Android subreddit today. Among the bits of info revealed by the team is the fact that OxygenOS won't be open source. Instead it will be a "real OS." Steve "Cyanogen" Kondik couldn't resist poking fun at that.
Cyanogen OS as produced by Cyanogen Inc. is not completely open source either, but it sounds like OnePlus is going for a more closed approach akin to HTC Sense or TouchWiz.
