Flash went away because Steve Jobs made an impassioned plea to find a better way and follow their humble browser which only had single digit percentages of marketshare at the time.

You're half right.

Yes, Jobs killed Flash. But he did it because Flash on mobile was a battery killer. And when the original iPhone came out (one of which I still have), battery technology wasn't as advanced as it is now.

Before I got my wife's hand-me-down iPhone, I had one of the few mobile phones that supported Flash. On the few occasions when I used the web browser, I lived in fear that I'd land on a web site that was using Flash because I knew it would tear through the phone's battery in less than 10 minutes.

Ever notice that the people on HN who pine for the good-ol'-days of Flash only remember games? Never the Flash ads and intrusive videos.

Jobs did the future a favor.
