It’s also just generally not a good train of thought regardless of the quality of the media or the individual person’s enjoyment.
For instance - my wife struggles to maintain an understanding of the story of whatever she’s watching unless she focuses completely on it, meaning if we want to discuss what we’re watching we pause the TV to discuss and then press play again. If we talk throughout something or she’s on her phone, she misses out entire pieces of critical dialogue or visuals that carry the story and so she ends up not being able to follow it and then therefore doesn’t enjoy it at all, or alternatively she has to ask what’s going on which kinds ruins it for both of us.
It makes no sense to make some weird inference that because of that, she’s somehow more susceptible to marketing or doesn’t know how to spend time with groups of people. Both are definitely untrue. I think it is fair, however, to assume that she probably wouldn’t be good friends with someone who is as judgmental as the previous poster, so at least they got that one right.
