Criticizing this video for emotional arguments doesn't make sense. It lays down statistics, quotes privacy policies, and chips at the way Mozilla uses emotional arguments in its marketing. And I've seen many Firefox people simply argue "the CEO deserves to be paid well" and "Firefox is the last bastion of the open web" - arguments that I myself have at least semi agreed with, which means I might have proclivity to emotion myself.
So if there's a problem... Can you cite specific examples in the video?
