Well the DRM software has to come from somewhere and Adobe has long proven themselves to be adept at such things for the most part. Are there alternatives? Is this because of Adobe muscling out others?<p>I found this [1] interesting:<p>&gt; Firefox does not load this module directly. Instead, we wrap it into an open-source sandbox. In our implementation, the CDM will have no access to the user’s hard drive or the network. Instead, the sandbox will provide the CDM only with communication mechanism with Firefox for receiving encrypted data and for displaying the results.<p>So the open-source fix for a closed-source, proprietary CDM is to sandbox it? How is this any different than Flash or Silverlight, really?<p>[1]: <a href="https:&#x2F;&#x2F;hacks.mozilla.org&#x2F;2014&#x2F;05&#x2F;reconciling-mozillas-mission-and-w3c-eme&#x2F;" rel="nofollow">https:&#x2F;&#x2F;hacks.mozilla.org&#x2F;2014&#x2F;05&#x2F;reconciling-mozillas-missi...</a>
