Several teams tried to get funding over the last two years to implement some kind of ActivityPub support in Discourse. As you well know, all such attempts failed so far.

- stop being aggressive about this and other related stories that bring only strife to anyone.
It you need a culprit you’re looking at things the wrong way.
