I think that's a really good point. When I see 'customize your feed' on sites that report the news, what I actually read is 'don't show me stuff that might challenge my preconceptions'. That's exactly what I don't want.
I've even blocked people on Twitter who I've never interacted with simply because people I follow keep retweeting their US politics stuff and I don't want to read it.
I do follow a few financial and international relations analysis people who I trust for reliable news. A manually, not automatically, curated feed. Otherwise I'm mostly reverse-engineering the news from the jokes made about it. And I get zero of it from Youtube or Facebook.
