While there are many failings of the CC in general, I'm inclined to argue that not watching TV isn't really a failing per se. In these times in particular, we have so many entertainment choices, that watching TV (as in putting on a TV set and surf through channels to see what they choose to broadcast at that particular moment) is itself something that seems to become increasingly out of touch with reality. Heck, he even has a (manned by others, no doubt, but still) Twitter account.
Now, granted, his decision to not watch TV is based on one of those somewhat holier-than-thou reasons that such people usually offer, but two things to consider here:
1: OK, so we found about this now, 25 years later, because someone asked him about his TV habits... Hardly what I call an in-your-face snugness about it.
2: He's the fricking pope. While the papacy is based on a lot of, shall we say, claims of dubius quality (like, you know, a particular version of God existing), being holier-than-thou is nevertheless their goddamn gig. And as such, "Not watching TV" seems to me to be a small footnote in a laaaarge book of popes being at least ten times more "holier-than-thou" than the current Frankie-boy.
