Adobe AIR / Flex Framework was probably also used for lots of intranet or business applications and not only browser based stuff. For these usecases AIR is still actively supported, and I guess a few companies still work on it and maintain their applications. I also know of a few embedded systems that used Actionscript/AIR for their graphical user interface. These also have a long lifecycle and need to be maintained. Although I doubt that most of these would get any new features.
