There are between 10 and 20 people actively working on the app in various capacities, there was an update on team structure couple of days ago - https://lemmy.ml/post/1372165 It is the original dev who is stepping down and who says he wasn’t actively involved with development for a while.

Sounds like the app is just transferring ownership and might rebrand.

Hope the developer is ok, sounds like this is weighing heavily on them.

The original author quit, but he said he handed over everything to other devs. So no need (yet) to state stuff like “going dark”.
