Ask HN: Article about pricing an online service at 1.4 * 1.4 of original cost

A little while ago there was a post here where the author argued that since the standard retail markup of some item is 140% of its production cost, online services should be priced at 140% of 140%. The details of the argument now escape me, and I have been unable to track it down via google or my HN saved items. Anyone know what I am talking about?
