The article isn't wrong, per se, but it offers a terrible strawman example. It is an example of OO done wrong, not a criticism of OO. The example offers a flawed data model. Each student is in a classroom, but it doesn't make sense to model the location as an attribute of the student -- unless it is actually a coordinate position. If it's a symbolic location (a classroom), it is much more logical to treat the classroom as a container; therefore it is the responsibility of the containers to move stuff around. OO tends to make much more sense once you analyze where the encapsulation should be.
