I partly agree. I've seen misuse in various projects : "Put at least one diagram of each diagram type (class, sequence, deployment etc.) in the spec cause we promised usage of UML!", "use case 'Enter street address', use case 'Enter name', use case 'enter birthday' instead of use case 'search for single person'". UML promised to standardize modelling/visualization but to me it seems not two people can agree on its specific purpose.
