Personalization does not arise from passive use. Consider the converse, articles from a list of user selected sources. That sounds more like personalized news. Besides Google News used to function that way so I think I should be entitled to my opinion of how it should function.
Oh, just found out that Google News has what you're looking for: go to headlines section.
I opened the app and found it weird that there were news about Taylor Swift, the British royal wedding and a lot of other topics that I'm not interested in. Then I noticed I was in the "headlines" section, and not the "for you" section.
