That's true, but you have to realize that Google, Apple and Microsoft all have to work much harder than Oracle to make their profits. Selling directly to the public is like that.

Oracle, on the other hands, sells only to other businesses. At this point, their reputation for being "enterprise grade" is so well established, they could probably sit still for a decade and still retain a fair amount of their customers. I don't think Microsoft, Apple, or Google could say the same for their businesses. Well, maybe Microsoft could, but certainly not the other two.
