This is a fascinating and well written long-form read about how the once darling of the web, Adobe Flash, has turned into its ugly step-child today.
There are a lot of reasons behind its decline, security being one of the main ones, but ironically a lot of it has to do with Apple slagging off closed standards.
On April 29, 2010, Jobs published an open letter called “Thoughts on Flash.” In it, he pointed to the closed and proprietary nature of Flash, which was wholly owned and controlled by Adobe and which required a browser plugin to use on the Web.
Now tell me, who has a closed and proprietary system Apple?
