In this here video, Mr. Mathew Moore, depicts some of the few most common and misguided information about linux. Mathew here, does not bash or troll in any way on linux and some of its advocates. He just shows in a very practical way, in the sake of linux itself, that info could be given a bit more carefully to the n00b or inexperienced user.
These are some good 20min of video. Watch them carefully. Kudos
