This is one thing I can blame them for, due to: media needn't be objective - that's not their mission - their mission is to make money, unless they're non-profit (how many of them is ?).
They use deception, to make you believe that news they produced is objective, and you shouldn't look for sources (which often are well hidden or absent), and assuming that news they produce is compatible with your worldview, you won't look for sources - you're their customer.
I'm sure you're able to divide media by political views they support - if they're objective why it's possible ?
The use of deception, means they're not good source of truth.
The main reason I found HN and stayed here, is its news quality (almost no political bs, and really close to the source).
