I'm perfectly aware of the history of diamond rings and De Beers' marketing campaign. I just don't think this analogy works very well, and it really seems like it came out of left field. The diamond-ring thing is really about following the crowd, and whether it's ok to ignore certain social customs because it might make your spouse's friends think you're cheap or uncommitted.
Blocking ads has nothing to do with people thinking you're cheap, and certainly nothing to do with commitment to a relationship, or your prospective spouse's opinion of you. It's only about whether you're somehow morally obligated to pay attention to advertising that comes along with something free. There's nothing at all free about diamond engagement rings.

it's a marketing swindle, not an analogy.
