Somehow I watched 1 or 2 videos on twitter right at the time, and got a good sense of what happened, that ended up being consistent with the jury ruling. These weren't even political posts, just some OSINT people I follow. I was not aware of any "misleading media narrative," since I don't consume any mainstream media outside of occasional twitter posts. Once the trial started I was actually very surprised how many people had zero clue what really happened, yet had strong opinions one way or the other.

This decision by Facebook probably does reverse something that was a mistake in some vague, ethical sense, but I disagree with the characterization that Facebook should be responsible for people's personal worldviews. You can't just give up all personal responsibility to Facebook and then complain when they do bad things with that power. They made a decision for business and legal reasons and we can criticize them from a business or legal perspective, but the narrative that "Facebook should have known better and it's their fault that people were misinformed" is just odd to me. It feels like a "have your cake and eat it too" situation with personal responsibility for being informed about the world.
