Today in 2014 the HTML5 specification was finalized. It ended the reign of Adobe/Macromedia Flash. While Web users run a lot of non-free JavaScript (e.g. YouTube’s HTML5 player), at least the platform is based on open standards and mostly Free Software. Flash is no longer required to display videos or consume web content of any kind. In 2011 Adobe threw in the towel on Flash and transistioned to HTML5 itself.
