Anything that "triggers" you (to interact w/ the platform), be it pottery or anarchy, FB will find "your people".
If you are prone to fits of passion, FB will find your passion-mates... mated to you by fear, anxiety, rage ... or joy.
Exactly -- and that's the real danger of algorithmic engagement-driven content.
For you, it's picking harmless content because that's what you engage with. But once you start engaging with, say, some crazy cult, Facebook's algo will pick up on that, and start prioritizing content from the crazy cultists. In time, you'll get to the point where you're only seeing content from the cultists, and come to believe that's what everyone thinks, because that's all you'll ever see. YouTube suffers from this too.
My suspicion is that journalists use Twitter more, and enjoy their audience and aura of authority they get through the Verified system, so they have an incentive to protect the platform against regulatory action.
