Hi Jane , in simple terms, linen is a superior fabric to cotton, even in household terms, such textiles, linen was regarded to last longer. With oil priming vs acrylic. The bond with oil primed surfaces is chemical and mechanical with acrylic primed. So the argument is, paint should stay bound to the oil primed surface longer than an acrylic surface. It’s all academic these days I guess, as it’s the source of a continuing debate
