There are two things working against standards in some market segments. One is that some de facto standards exist but they are copyrighted and the owners refuse to license them. Any attempt to clone the standard or its interface often results in a gigantic lawsuit. (See Oracle vs Google re the Java interface.) The other is that large companies develop such a huge corporate ego that they think they can ignore standards due to market share. MS was often guilty of this in days past. Google and Apple are the new heirs apparent of this phenomena. Standards eventually win out but only after widespread acceptance of standardized products in a commodity marketplace or after governments step in to regulate the market.
