The other reason could be imagine if a company that you really liked and used their products, like Apple, and all of a sudden they declared they didn’t like the technology you used to make your living. Then all of a sudden, people in the web community and outside of it, were saying that technology was dead. Imagine if you’re a FedEx delivery person and the post office declares that they have a technology that makes your job no longer needed, not only that, but other people are actively celebrating the end of FedEx. That would kinda suck. Although, really, any person that actually knows anything about Flash, HTML5 and web development knows that Flash isn’t done, it’s just moving on to other things.
