I find two distinct reasons why people may dislike or speak against a news source :
1. Quality of investigation, journalism, writing, reportage
2. disagreement with overt or subtle position, bias and perspective
Fwiw, Without detail, your comment is automatically presumed in category 2.
I for one find guardian very opinionated and biased, but eminently readable. It has a very overt perspective, but it generally has good quality writing. I would not make it my only / primary source, but I don't automatically shun it either.
I automatically filtered it out precisely because I believe what the (interestingly downvoted to near white) parent says; it's closer to an entertainment source than a news source. They picked their audience, and the headlines are written accordingly, then follows some words to make up the article — or at least that how it always reads to me.
It’s not that much worse than the daily mail. I don’t think biased news is failing. On the contrary, the more government spending follows fake news suppression, the more profit in biased news. See American tv news for the same general trend.
