It's an obvious conclusion, but I'm not sure that it's a tautology. The name of something doesn't define what it is, only tries to describe it. As others have pointed out, it is, for example, perfectly possible to be interested in an adblocker mainly from a security point of view, without taking any position on ads themselves.
