I really wish instance admins that have decided to shut down their instance, would first offer to transfer ownership to someone that's willing to take on the task.
Sometimes it doesn't work very well because the admins have different idealogies that don't match, leading to a bad experience for users post transfer.
However, maybe that risk is worth it, if sometimes it works out.
Certain domains that have come and gone over the years were REALLY good for Fedi instances and it just sucks seeing them go to waste.
