This blocked the sale of OnePlus One phone in India until this could get resolved. OxygenOS was the answer to this. Fork of Cyanogenmod with some rebranding and a few added things.
Personally I bought the OnePlus One because it came with Cyanogen. I wasn't happy with all the added cruft in CyanogenOS, so I reflashed to Cyanogenmod soon after a stable version was available.
I'm currently using OxygenOS on my OnePlus 3, but will flash to Cyanogenmod eventually to run more bleeding edge and get some features back that I miss.
This shouldn't effect OnePlus 3 as they terminated thier agreement with Cyanogen Inc after the India licencing problem.
It's boggling there has been no official word from Cyanogen Inc on why this happened. I never liked the OnePlus marketing or press, plus I had a OnePlus One with that terrible grounding/touchscreen crazy issue.
Just judging from OnePlus's support, I have a feeling Cyanogen was getting sick of them too. I'm sure there's much more to their fallout than what's been made available. Considering my experience with OnePlus's product, I'd probably side more with Cyanogen.
There was a lot of controversy in the open source community about Cyanogen's partnership with Microsoft. It seemed like good idea when you think of Microsoft pushing more Android products and their internal divisions trying to break away from their own failing phone market. But I guess that effort failed as well. Did they ever release any phones with CyanogenOS + Cortana?
that isn't exclusive to OP, though, of course - every other vendor I can imagine does the exact same to any non-hardware customizations they apply to the OS.
