Well, it's not a problem with Facebook, it's a problem with people and our society, Facebook is just serving their customers' needs. If you tolerate only one point of view, if you accept and get engaged in only one line of political discussions, and actively avoid and try to shut down anything and anyone with a different point of view, entirely detached of any self-criticism, then of course that it's exploitable to serve you false news (and much more BS than just news). People deliberately choose to live in these info bubbles because it's easier on them emotionally. When nobody questions your views you are always right. Also, it's quite easy to avoid this trap by listening and reading what other people are saying and writing, trying to understand them, and by always fact checking their claims, but also your own beliefs. But it takes some mental effort to do this. Therefore, most of people are not ready to do this, they don't care. You can't fix this without fixing the society first, and not Facebook.
