I come across this response quite frequently and I remain mystified why anyone would think that it's important or even a good idea for the millions of people interested in privacy to try to solve privacy issues from the same angle. Skillsets don't even fit for this: as a developer I am well-suited for working on network technologies that don't leak information about their users, but a lawyer for example is much better suited at changing legislation so corporations are responsible for protecting privacy. We don't need a "focus", we need everyone to use their skills to protect our right to privacy.
