I'm with TexasTom here: I'm a long way from Washington, but having been very active in the DTV transition and having talked to a lot of viewers at the time, I don't see it as a matter of stupidity or divine guidance. DTV reception can be confusing, OTA reception is unfamiliar to a lot of viewers in all areas, whether urban, rural or suburban, and viewers can use all the help they can get.
(This is especially true because the viewers being addressed by the FCC's Q&A sheet are, by definition, the viewers who'd been using cable or satellite rather than OTA reception.)
