> Is facebook wrong

I think this is an unhelpful framing of the situation, because as you imply Facebook is of course not wrong.

If you have one friend and your feed is entirely full of their posts, Facebook is off the hook. But, for most users, the situation is far more complex. People have many friends, they may also be in groups. They probably will not be on facebook long enough for them to see all of the posts and, if they are, their attention levels will differ over the entire corpus.

In this situation facebook begins to have agency - which is different from being wrong. They didn't make the content, they didn't create the link that brought the content to you, but of all the content they could show they did show you this and not that. It's a relatively new kind of agency, one that we didn't have a lot of practical experience with before very recently, so they can be forgiven somewhat for their difficulty grappling with it. However, they're an important part of the chain of information organization and it would be foolish to pretend they have no responsibility.
