This time is probably unrelated to @ernest's supposed inactivity. Actually, his another /kbin server, https://karab.in has been brought back on 15 of February.
Posting the same link to 3 magazines is enough IMO. Your /kbin account can be followed via Mastodon and similar services, and Mastodon interprets crossposting as completely different posts.
Sublinks, crafted using Java Spring Boot, stands as a state-of-the-art link aggregation and microblogging platform , reminiscent yet advanced compared to Lemmy & Kbin.
But the author of PieFed, written in even more popular language than Java (Python) said:
The thing with the more twitter-style ActivityPub projects is they send activities to individual users inboxes a lot, whereas with the threadverse it's all shared inboxes. So there's a fundamental difference in the way they use the protocol which makes scaling those projects much more difficult. My gut feel is that adding full microblog support would increase the size and complexity of the codebase by at least 50% and triple the server load. Maybe much more. It just doesn't seem worth it.
A feature creep?
(maybe they see a bus factor = 1 as the only issue of /kbin, though)

According to https://fediverse.observer, these are largest threadiverse instances by MAU (but pay attention to different method of counting active users between instances...):
