How? They are just links to original work in other places. Now if you look over all media there is a bias in the US Republicans will see all non Fox as left wing in the UK all the papers are right wing.

I think News looks at what you choose and offers more of the same.

They are biased in the work that they choose to present. Curation is a way to introduce bias as well. Doubly so when you consider that they post the headline as a notification, and most people stop there.

I don't have specific examples, I'm just going off the several times in the past year where I've seen a news story covered in five different ways, then I see an incredibly slanted headline notification from apple news that is woefully inaccurate.

Also, Fox is just the other side of the same coin- left or right wing, when it matters, Fox is no different from CNN. It's all fake garbage. Just wait until you're belief systems or personal experiences don't exist within the mainstream collection of proffered views, and you'll see how fake all of it is.
