Thank you!
A scary thing about the Fediverse right now is that some instances have many of the bigger communities. And the owners of the instance can literally shut it down at any moment (or stop federating with you).
And right now there isn’t an incentive to keep instances alive.
The thing is that right now it’s not worth it to buy a raspberry pi if you want to selfhost. It is 4 years old at this point but it cost 50% more than when it was released.
