It only "makes sense" from the perspective that users are not allowed to have zero set top boxes from the provider themselves. And that's because the cable companies fought FCC's proposal to allow any set top box to act as the main set top box. My point is, the same people who now use Roku likely don't want the Comcast box. They want to use Roku as the one and only box, but Comcast charges them "for having two", even though they leave these customers no choice but to use two since the first one is mandatory.
