I believe that's what it is called. I didn't read TFA but it sounds like they are claiming that Google is not doing anything about the problem. Not true. They have started putting things you might expect in the OS in a downloadable app. Then when it needs to be upgraded, they put a new version in the store and you get it. You do not need to wait for your carrier/manufacturer to provide an upgrade.
They are also unbundling stuff from the OS like the browser. Several years ago the browser was part of the OS and recently a security issue was uncovered in it. Google declined to fix it knowing the possibility that manufacturers and carriers would roll out an OS update. Today the browser is Chrome and it can be updated separately from the OS.
Both strategies allow Google to bring new features to older phones regardless of the lack of diligence on the part of the carriers.
