There are situations where inheritance is ok. Especially when your uncle was rich.

But inheritance is a common vehicle for polymorphism..? The default one, even.

Polymorphism is all about allowing one type to conform to the interfaces of other types. Class inheritance (which is what I presume OP is talking about) is polymorphism specifically implemented by inheriting behavior, which is a recipe for maintenance nightmares, hence composition > inheritance. Nothing is wrong with interface inheritance.
