After what Twitter, YouTube, and Facebook did to block Trump's accounts, I imagine they will go to full deletion or even more insidious, modifications, when they start going after those responsible for censorship. Q drops also mention of these companies coordinating because of connections with Epstein (or implied). Backing up the data now would be a good move since it would preserve any evidence or historical doing so that what Trump has done in office cannot be manipulated to be viewed differently
