Where I am getting frustrated with this article is the notion that this is a big win for Google. I have to disagree. Google or alphabet or whatever they want to call themselves may have created the android OS, but they release it in an open source format. They do this to get it out there on as many devices as they can. More importantly, they do this to get it into the hands of as many developers as they can. There are a number of things that I actually thought were part of android, that only later when reading stock android was adding certain features did I realize were actually only part of CM. That's really what open source is about, the ability for a wide variety of people to work to better something together. A lot of times things seem to make sense when one person is working on them, but later we come to find out that they don't make sense to others.
If Google actually wanted to rein in android, they would simply retool with proprietary code, and release the next version of their OS closed source. The only thing they actually seem to be concerned with are phones that are still running old versions of the OS. This makes is hard not for them, but for application developers to support their applications in that ecosystem. We have seen Google take steps in the recent year or two to modularize some of the core components of Android so that those pieces can be updated even if the OS itself has not been.
