The problem with the FOSS options for these services is that they're a PITA to set up or use, and they usually cost money. It's not like using a FOSS alternative to Photoshop, where you just download Krita or Gimp and run it locally on your PC: with a service like Mastodon, it needs always-running servers, so you either have to have your own server on the internet (not really viable for most people), rent one from a colocation provider or other service ($$$), or pay a subscription fee to keep your instance on someone else's server ($). Now compare this to using Facebook, which is free. And since there's zero interoperability between different SNS services, you have to go where all your friends are.
