I spent some time trying to figure out what happened to Shumway, a while ago. As far as I can make out, Mozilla figured out that with the amount of resources they could afford to put into Shumway, by the time it reached the point where it could generally play most Flash content, nobody would be making Flash content anymore so it wouldn't be a notable feature for Firefox. There's definitely still value in something like Shumway for viewing legacy, historical content, just like there's legacy in browsers being able to view old Geocities pages. But it's never going to be a feature of significant commercial value.
