I think people in general are pretty OK with the data hiding part of encapsulation. Scattering application state across objects as part of encapsulation, and polymorphism and inheritance are the source of a lot of debate though. Bob Nystrom wrote the best description of the polymorphism vs. pattern matching tension I've ever read [1], and I think problems w/ inheritance are all pretty well known (method resolution, programmers becoming taxonomists, etc.)
