Mr. Cook is the CEO of a corporation. If you don't like his company's news aggregation app --for whatever reason-- then it's easy enough to round up some other way to fetch "news you personally can use".
My point here: Your view of Cook's company's app's views are not necessarily an objective assessment.
Since I dare say so, I'll say this: it's also possible that Cook doesn't have a lot to do with whatever shows up in that app's offerings. Honestly the man likely has better things to do than micromanage content of a news aggregator. For instance I'd like to think he's had a hand in shoving an upgrade of the Mini to a higher place on Apple's to-do list...
For news: what I do in picking my own "window on the world" is subscribe to assorted briefings, with whose authors I may find myself either rarely or often in agreement. I choose those briefings because they in turn highlight assorted events or reportage that they find significant, and provide links so I can read them and decide for myself what I think.
For instance I like Politico's labor briefing, Morning Shift. And, I like the Financial Times' myFT mailing, that briefs me on categories of topics I can tell the FT I like to follow just by reading assorted pieces in the paper itself. And, I take an email from a Massachusetts congressman (I'm not from his state) because he details votes taken in the House.
And, I subscribe to a variety of publications that inform me from the right, left and what I call "irrelevant lean", i.e. a few magazines I take because I just happen to enjoy some of their long reads, like those in The New Yorker, i.e. articles that may or may not be of a political nature. I do confess to liking some of the ones that end up on the political side...
lol and sometime even though i haven't a Facebook account, I check in to The New Yorker on FB for a video now and then. Here's a video of the guy actually doing the copy editing that my link above had resulted in.
Sorry for the slight drift there but I really did want to point out that if you don't like the Apple news app, you can find stuff much more to your own liking, and have a lot of it funnelled to you through social media picks or email briefing preferences. Personally I try to take news from a variety of sources so I know I'm not choosing to ignore the world at large.
