It's not cognitively possible for a user to simultaneously view every piece of content. Someone has to make a decision about what goes at the top. Of course, users aren't passive, they could get their news elsewhere or change the filtering. But we know that defaults matter a lot. For many people, the order in which platforms present news is going to be profoundly influential. The inescapability of choosing defaults settings, and the empirical fact that default settings do influence people a lot, taken together, imply an ethical responsibility on the part of platforms. Making people smarter would be great - but you've got to be realistic about how effective that would be, and how long it would take. What other usability problem would you solve by changing the people rather than the technology?
