Even the sandbox isn't free (or even open source) software. The CDM checks  
the integrity of the sandbox, so you can't modify it. Even the open source  
definition says that "people need to be able to experiment with and  
redistribute modifications."

So despite their claims, the browser itself include nonfree/non-open-source  
software.
