> The fact checking was pleasing the left, and now that the right has the power, this left-wing-propaganda thing has to go.

Yes you understand. Meta, due to its problems with moderation over the years, both legal and political, has largely ceded direction of that to the government. Previous government wanted things like fact-checking, an oversight board for moderation decisions, and censorship of certain issues. Current government doesn't want any moderation at all, like X, the social media owned by Trump's biggest ally, which he personally loved so much that he created his own Twitter clone when he was booted off of Twitter. So in that environment, the easiest, simplest thing is to treat Meta platforms like X. That's all there is to it. It signals commitment to the new administration, it heaves political and legal pressure off Meta, etc. much more than your suggestion, that they keep fact-checking but bias it towards the right (which would need to be explained to the administration, etc.) Just saying "We're like X now" gets the point across most cleanly, and it's cheaper
