In my opinion, being able to code and make things without the use of proprietary software will usually become more popular in the long run. With JS if necessary I can pull up any text editor if I had to and edit any file, with Flash there's a higher gateway to entry and a higher learner curve of sorts. It seems the the crowds will adopt the way of open in the long run. To me HTML5/JS just seems more natural and a prettier way of doing things.

You dont need any proprietary software to code and make flash. Just use the flex compiler and code in any text editor. The flex compiler can do flash apps without flex also and has some pretty nice sintactical sugar things like two way databinding if you want it.

Other than the fact that the only way to test, run, and debug your applications involves using the closed source Flash Player...
