How? It was never a Flash vs HTML5 competition. HTML5 was always the next iteration for web content platforms. The only thing SJ did was abandoned current technology for HTML5 at a much earlier stage. If anything he accelerated the adaptation of HTML5, but even that can be disputed cause HTML has always been used as a "low bandwidth" alternative to Flash sites -- not cause of apple products -- its because a lot of other countries are still catching up to higher speed infrastructure. So even if Apple didn't exist a move to HTML5 would have happened nonetheless.
