I really hate the access control on Fediverse quote posts. If you have a public post and you opt out of quotes, the following are possible: Posting it on a web site and inviting abuse.Posting it on Xitter / ColourSky / Instathingy / ClokNoise and inviting abuse.Posting it on Mastodon but as a link (which shows up with almost an identical UI) rather than the quote post and inviting abuse.The following are not possible: Automatically notifying the original poster when you have quoted it.For private and follower-only posts, controls over quoting should be limited to options that extend the permitted access (for example: my followers can post this follower-only post as a follower-only quote post and then the transitive closure of my followers will be granted access). The current model added a load of code churn to ActivityPub implementations with zero benefit.
