Linus adamantly refuses to offer any kind of long-term guarantee. He got flak for the warranty on the backpack for that reason; there are plenty of competitors selling bags at the $250 price point that back up their offerings with long or even lifetime warranties. When pressed, Linus put out a mealy-mouthed "oh I don't want to open up my family to liability" statement which both managed to say absolutely nothing (why would his family be personally liable? LMG is a separate entity) and shame critics. It seems to me Linus personally can't handle criticism, like at all.
