They either don't understand OWA or they take time to understand it and then decide to ignore it, because they don't need OWA ever or there are parts of their processing where they don't need/want it. They decide to 'close the world' themselves sort of say. They do need a modeling language for declaring classes and properties. OWL has it, so they use it. In my experience, majority of people do something like this.
