There are design patterns to prevent this kind of thing. Simplifying it to inheritance vs composition is a bit reductive, although I completely agree that composition is usually more powerful. You could have easily solved this problem with interfaces as well though.

Inheritance could've achieved that. That example of inheritance was deliberately wronged.

Inheritance could've achieved same thing with same constructs (Runnable, Swimmable) where these would be Virtual classes.
