It's some weasel word bullshit. Facebook admitted that promoting HCQ did not constitute an act inciting imminent physical harm, and thus should not have been removed. That's about it. They admitted they overreacted by removing a post, but only on technical grounds.

All the drugs theyve discussed work, they work well early in the disease and less well the longer you wait to treat. But they knew that all along.
