Is FC practically any different from X in this regard? 

In both, you can delete your content from the network, but people can preserve your content against your will be screenshotting or using APIs to download.

It's materially different. It's extremely hard, if not impossible for a third-party to archive everything from Twitter. 

But for FC it's so easy (by design) to have the full global state - I just need to run a hub (and make sure I don't delete anything)
