Recently I had a problem explaining to a recruiter why I am designing only UI, Visual language and care only for visual parts of the product. She didn't react at all when I started talking about "Dark Patterns":) It is requirement nowadays, it is not optional. If you as a designer don't think about new ways to exploit the user base, you are not worth your salt. I moved only to visual stuff for two reasons: 1. Designers used to think about the user, functionally and aesthetically. Nowadays designers who cannot draw a straight line move templates around and comply with the management without any form of critical thinking. 2. There is no way for me to be a "writer" and do the dishes. Yep, nowadays designers must not only code but and write compelling stories to be hired. Utter nonsense.
