You're discontinuing Adobe Story for a few reasons, one of which is because not too many people used it. Please realize that people don't want to place their screenplay(s) on the internet when NOTHING is 100% secure online. A lot of people need screenplay software that would allow easy, automatic placements of camera shots, lighting, notes and so on, but will not risk having their work online when people have the ability to hack servers.
Imagine the screenplay to The Avengers: Infinity War, a movie that made over $2 billion, was stored in Adobe Story, and then someone hacks Adobe and posts the screenplay online for everybody to read before filming even began. Screenplay software ALWAYS has to be confined to people's personal computers, it's a no-brainer.
