Did you inform your users about the reasons you were shutting down? If they had an explanation I see no reason for the anger, but if you just shut down one day then it is more understandable.
Well done though, you’ve done what most of us will never do and you’re still looking forward, good luck with the future.
Well I’m glad to see you’ve kept on with it. Hopefully if there is ever another rug pull you’ll be even better equipped to keep going.
