I think it comes down to how you use it. I have seen people write entire systems in DOS batch script. Was that a good idea? Not really. Can it be done? Oh very much so. But is that the fault that DOS batch script let you do that? Not really. OOP is the same sort of thing. It is a tool. You can take the abstraction too far and make it miserable to use and extend. It depends on the team/person doing it. Perhaps they are fine with 'too far' the next poor soul to come in may not be able to keep up with the 13 layers of abstraction that they had no decision in. Where is that line? That is more art than CS as the rule is 'it depends'.
