I gotta say I read the article and it didn't make much sense. It seemed to make a lot of loosely connected accusations without any external evidence to back them up. I lasted three minutes into the video and heard just more of the same.

I bet Mozilla does have a ton of problems. They're a non-profit that has been around forever and has more reputation and influence than its undersized user-base would imply. That's going to make it a weird organization. But before I would go so far as to believe that "Firefox cannot be trusted" I'd need to see some harder evidence.
