This is tricky, because it's a very easy thing to convince oneself of, given the desire to do so. From my experience, I don't think that particular misinterpretation of the interference is unusually prevalent. In fact, it might even be less prevalent than "normal", considering how these things usually go. My pessimistic side expected far more calls of "Russia changed the votes!" than there are. What I've actually seen in news and conversations a surprising amount of the time is a more accurate definition of the scope of what did happen and what we don't know.
