A big problem is that university teachers are sometimes stuck 20+ years ago and teach that to students every year - one teacher can hurt a hundred+ students every year. And then we have to undo the damage when they join the workforce. e.g. take this example (sorry guys if you see that, I googled for PassagerStandard) : https://github.com/sbrouard/public-transport-manager/tree/master/TD6/FabriqueTec/src https://github.com/sbrouard/public-transport-manager/tree/ma... - during a whole semester you model a freakin bus with different "passengers" - "standardpassenger", "stressedpassenger", and the bus stops also have behaviour modeled by objects like "CarefulStop", "PoliteStop", etc... The whole thing is basically worst-case OOP where everything is modeled by an interconnected mess of objects and every exercise becomes just worse and worse than the previous. And students have to learn to do that every year and are judged on how "well" they did apply OOP techniques in order to graduate. (note to reader - the authors of this repos are students who had to implement this mess, not the authors of this exercice)
