Great statement by someone who doesn't understand the majority of women. As with most things, women care a great deal about the social aspects of watching TV, discussing what is happening and what is going to happen and what just happened. If I pull out my iPad or laptop to watch something else (or as is common in my case, play video games), and I plug in earphones, she loses that aspect and it isn't as enjoyable for her.
In fact, I wonder if that is at least part of the cause of the lopsided ratings. Women might care less about the show and more about its capability to discuss it with others. Despite enjoying Sex in the City, she wasn't very enthused when I got her a copy of the show because I wasn't really interested in watching it with her. I tried watching the first episode with her, and found it rather hideously boring. The show is off the air, so none of the women she knows is going to be discussing it anymore. When it was originally on the air, lots of women (and I believe it was a hit among gay men as well - and before the outragists here start shouting, these are generalizations) were discussing it. It probably doesn't hold up as well now, and I be interested to see the plot of ratings over time.
Ultimately, it seems like this information is just a stereotypical conflation of correlation versus causation. There are gendered differences to the rating, so there is a leap to the unsubstantiated reason of "sabotage". The true results of this study should be, "Hey, I wonder why this is?"
