I think, one of the reason used against this feature from way back in 2016 (when Mastodon first came out), was that it disconnects the conversation. Once it's disconnected, you do not know what's happening (borders on moderation already).
I remember saying then and now that it doesn't have to be. A QuotePost/QuoteReply can still be shown within the same thread.
Since it was all about choice and permissions, I suggested the following: Original Poster
toggle: disallow quoteposts/quotereplies (default is false)
if above is false, then, toggle: allow quoteposts attached to your thread (default is true)
QuotePost/QuoteReply
if “disallow quoteposts” == false && “allow quoteposts attached” == true, then offer
toggle: disconnect from the original thread (default is false)
I would like to think that most would keep it ‘false’. And if “toggle disallow quotepost” is true, then the only way is to manually copy the link into a new post (not using the quotepost feature itself).
It satisfies the OP's desire to make a decision about quoteposts/quotereplies; while at the same time, it also satisfies the freedom of the other users.
It isn't perfect, and it's probably not a good idea to implement this level of control/permissions. But, I think it addresses the concerns of both parties in the debate.
I, for one, would prefer quoteposts/quotereplies to be attached to the original thread. But, at the same time, I want to give the users an option to ‘disconnect’ from the original thread.
Anyway…
When you are quoteposting/quotereplying to a thread in #Calckey, the quotepost/quotereply still shows in the original thread, like this one, when viewed from Calckey. It doesn't when viewed from other #fediverse / #MycelialNetwork software.
