A secretive group named Occupy Flash has set its sights on Adobe, in particular it's Flash products.
It's well known by now, that Adobe has discontinued its mobile Flash support, and will only continue working with its desktop applications.
Flash has been the proverbial sliver in many peoples thumb for a long time, due it's crashes and security issues.
As I already mentioned, Adobe has discontinued support for its mobile products, but that seems to little for the Occupy Flash group. They are also targeting Adobes desktop products.
HTML 5 is the preferred choice for developers nowadays and for the future.
Occupy Flash thinks that way as well, but denies there movement being an organized attack by Adobe competitors.
