If we've learned anything over the past year, it's that tech companies have no business deciding what is factual. "We're going to decide what's true, then make sure people only hear what we want them to hear" is just deplatforming with extra steps.
If you follow the link, it's talking about Facebook reverting a temporary change that penalized "hyperpartisan" news sources. That's not quite the same as FB deciding "what is factual"; it's FB deciding what news outlets are "hyperpartisan". It's still on the same slippery slope, but it seems like the cost:benefit ratio is far better, if you keep in mind the status quo -- regardless of which side of the left/right divide you may be on, you'll probably agree that the people on the extremes are nuts. (Yes, you will have a different opinion of what is "extreme", but the hyperpartisan outlets are in a feedback loop that rewards greater extremism so there's a fairly stark separation between left/right-leaning and the extremes.)
