I don’t think that the connection here should be dismissed outright; I agree that just as news has bias, and clicks drive profits, so too can news drive profits and therefore be considered advertising. However, I think, as another commenter has pointed out, you maybe could serve your argument better by digging deeper into the examples in the pattern of behavior you believe to have exemplified here and ask, “Why?”
For example, in the only example you dive deep into, its important to ask: why would Have I Been Pwned,” a website I understand to be donation driven not-for-profit service and only takes in an email and spits out hits on already released data, have any incentive (or money) to get a news article published about them? This service doesn’t have any benefit to have more visits.
I think one thing you can take from this community is that there is one word that holds the highest value among people who attempt to better themselves as rational thinkers: *reconsider*. Yes, you have reconsidered the incentives of new agencies, but what of yourself? You say that the relationship between your happiness and news is not subjective, but aren’t all feelings subjective? Could it be the case that you are a less happy person when watching news because the news is, simply put, largely negative? Or perhaps that you, like many including myself, feel powerless in the face of negative news that is far away? Could your new sources be less biased or more diverse? Couldn’t it be the case that seeking out authors that have beliefs that align with you could challenge you less as an intellectual, and therefore be less productive for your mental broadening even if it feels better?
Reconsider all things. Delve into the “why”. And do not eschew that which makes you uncomfortable simply for comforts sake; take the news, blog or mainstream, with a grain of salt and a healthy dose of skepticism, and when you are going for good feelings my advice would be to avoid all news and just go do something you enjoy, like writing!
