the fediverse chases away developers over "privacy" while broadcasting posts to thousands of servers.
you can't have it both ways.
if you hit Post, you lost control. that's not a bug, that's the internet.
If you have a fediverse account, you can quote this note from your own instance. Search https://mastodon.social/users/dansup/statuses/116222565495061519 on your instance and quote it. (Note that quoting is not supported in Mastodon.)

People never understand that activitypub is fundamentally built for public data, any privacy controls have been superglued onto it and basically amount to good will behavior on the part of servers.
There's not actually anything preventing a rogue AP server from boosting private or follower only posts, for example.
Fedi is not the platform for privacy.
