#Threads is attempting to communicate the inclusion of quote posts in their AP messages.
Unfortunately, there’s not a true agreed upon standard for quote posts. Some #FediApp developers have made an agreement amongst themselves as to how that should work. Threads is not following those rules and has decided to use a _misskey_quote attribute in the AP messages. This isn’t coming across in the quote post format in most apps I use.
