Sane people do not necessarily have the level of education to judge the show moderated by BG correctly. Many watch it just for entertainment. BG is widely known and popular. Thatīs enough for marketing. People with proper education can judge the tool. If it performs and has a reasonable price why not buy it?
Face it:
People like BG because the show has spectacular stunts. They talk about it so more people get to know him. People like Les Stroud or Doug Ritter are almost unknown on my side of the pond. Their information may help to survive but "play it save" is pretty lame if you want some entertainment.
