I take the video with a grain of salt of course but just to be fair here, the video spends the majority of its time explaining in great detail why Linus did NOT just slap his name on a megapro screwdriver. I actually found the minute details of how they designed, prototyped, and stressed over the screwdriver quite fascinating and while it may or may not translate to quality... it at least is a weak signal to me that someone considered every facet which I believe is somewhat correlated with quality.
