All your "free thinkers" that are browsing these posts for 5 minutes while they take a dump won't be taken in by the mere stamp of authoritativeness on the fact-check posts, right? I mean, obviously all users are able to make good judgments and competently weigh all the facts on every topic. Why are you so worried? What makes a fact check post more authoritative than NASA?

Btw I'm not advocating for active suppression of ideas. I just understand if a particular company chooses to do it on their website. I'd do the same in their place. It's not their job to give everyone a voice.
