Flash wasn't deprecated out of opposition to multimedia/interactivity, it was deprecated because it was proprietary, insecure, and difficult for old people to install. The plan with HTML5 from the start was to allow normal web-devs to do things that previously required Flash and work on HTML5 started long before Flash was killed.
Unfortunately, all that HTML5 interactivity fails to do the one thing Flash was great at - allowing tech illiterate retards to make interactive webpages, art, animations, and games and distribute it all in a convenient format. It used to be possible for any idiot to pirate Flash and have a nice, visually intuitive GUI for throwing together interactive animations of poorly drawn women choking on cocks, and the end result usually had a low file size and could be distributed as one file for reposting on /f/! Now that same retard would have to learn Javascript (and figure out how to integrate his code into his animation without a nice GUI to help) or abandon the joys of interactivity in favor of making a normal poorly drawn animation (far less fun).
