Isn't that the case for every language with polymorphism? Even C, once you add function pointers to the mix.

I've certainly heard polymorphism and OOP criticized on these grounds, but unless you're a hardcore kernel or embedded developer, that ship sailed about 25 years ago. Everybody uses debuggers and log statements these days. Expecting to be able to look at a code sample in isolation and know what it does is unrealistic for any large-scale system.
