I'm not 100% sure if previous poster is annoyed at the same thing as me, but if that is the case, we're not annoyed at the newspapers not giving names to their anonymous sources.
It's when they do science reporting and say "a new study says blah" without linking to the study. Or they paraphrase a law proposal submitted by some lawmaker without linking to the original text. Or they repeat something they got from another news source without pointing it out. And even if they do, as the previous poster mention, it is subject to link rot. Frankly I think they do that because of the attention economy. Less eyeballs leaving their site.
