You have to own an internet-connected device and have internet access. My point is, Facebook is a de-facto standard for almost any non-technical community these days, and if not Facebook, then it's some other social platform, like Whatsapp or Telegram. Turns out, centralized platforms are much more user-friendly, have better network effects and easier to set up and administer for majority of users.
