The term you are looking for is Confusopoly which is becoming a standard response by large corporations when they product they sell is a commodity with no discernable differences (worth noting anyway). As databases become a commodity, even given away for free, it becomes harder to differenciate on cost/performance/features. So just confuse the customer! This tactic is mainly used to retain current customers as opposed to gaining more, in that the customer can't easily see that the current product is compeditive or not. Witness mobile phone plans, Utilities etc to see who the confusopoly is taking hold!
