Facebook can't magically fix your feed for you, you have to curate it yourself, how come people don't understand that?

Now then.. are we all so stupid, or is Facebook ran by a bunch of scumbags who care only for "user engagement" no-matter-what? And it may be that some people get confused by its practices, then understand the dishonesty that is causing the confusion and give it up (abandon FB), while others get trapped in it, so net-net FB made more £€¥$ and kept the bad practices.
But at the end of the day, the source for your feed is what your friends post. If all your friends post nothing but cute baby pictures, your feed is going to be 100% cute baby pictures, and nothing else. If your friends post nothing but cute cat pictures, it's caturday forever on your feed. And if your friends keep posting political bullshit that you hate, then that's what you're going to keep seeing.
The position I don't understand is the one where people endlessly complain about how Facebook has turned to shit, and then expect Facebook to magically fix it for them? That's never going to happen. Either curate your feed, or stop using Facebook. Those are your options.
I don't care that they comment on some post to win some product, or is tagging a friend in some viral video. I don't want my feed to be full of fake engagement. But I guess that's all Facebook is now, as no one really posts anything anymore, so that's what they show to make it seem things happen.
Saying if everyone posted only agreeable stuff it would be fine is an impossible scenario. Nobody has friends that all post exactly the same thing all the time, and nobody is going to eliminate all their friends that aren't exactly identical. And you know, if you got nothing but saccharine positive thoughts and "law of attraction" style BS, that would be unbearable too.
The well known saying is that "the poison is in the dose". Facebook can concentrate virtually anything into a toxic dose.
If I have interesting content, that I wish the maximum number of people to see, then why wouldn't I make it internet-accessible?
Consequently, what's left is (a) people who actually want access to the userbase (e.g. advertisers) and (b) people too technologically limited to avail themselves of other options.
You can tweak the engagement algorithms all you like, but boring content is still boring content.
The resulting noise keeps users reliant on the algo for a coherent experience.
When everyone sees a chrono feed by default, their own conduct is informed by the behavior they like/dislike in others. For example, I remember ~10 years ago when posting a picture of your lunch every day was widely understood to be poor form, precisely because it diluted everyone else's experience. It's a bit ironic that it's become a legitimate use case for instagram.
Chat and stories are what most people want and use.
