I guess they are unable to value the function that I am more likely to read and trust stories from their website if they give me the honest info about where their stories come from that I can further read (and rely on them to always point me to as a guide).

they likely, and probably correctly, do not want you as a customer. people who are discerning and conscious like this generally use an adblocker, and even if you don't, are generally less easily influenced by adverts in the first place. most people like this tend towards wealthy, so it's a valuable demographic if they can get past those two issues, but they're not easy to get past

Most consumers cannot identify which website they are currently looking at. Google, Facebook, giveuscardinfozzzz.com, all the same. No distinguishing or discernible features or difference.

People like you are factored in. There just aren't enough of you for your preferences to impact editorial policy.
