When you post things on Instagram, Facebook, and X, this is what they look like to people who don’t use those platforms.
@felwert @aral On Mastodon, you can make a post "only for followers," and we're fine with it. I can imagine that a user can decide on his personal level not to share their post with the open web. That's their choice.
(Though, the funny part is that it's more like a flag, and respecting it depends completely on the app, so if there is more traction for Bluesky, apps going around that might start popping up. Same for blocks.)
