Adobe Confirms It Will Abandon Flash Player Mobile

Flash did fail on its own accord. If Flash was good, Apple would have included it. It wouldn't make any sense for them not to include it if it was dramatically superior. But it wasn't. It was a terrible, inefficient, and clumsy. Apple even stated they'd asked Adobe to show them a version that worked well for years and was unable to.

Adobe was unable to produce an acceptably performing version, that's the end of the story. It performed mediocre-ly on some Android devices... for video, at least... and terribly on everything else.

Apple railed against it, Microsoft didn't support it, and Google had no interest in it aside from a cheap attempt to prove how 'open' Android was.
