This is very sad to read. Made an account to share my story.
I posted once on the other forum when I was looking for a new grinder. The Niche Zero was in early IndieGoGo days. Dave recommended it, but said “no need to take my word for it, come round and have a go”. I was shaken by his generosity. I took him up on it en route to a family meet up. He showed me his roasting set up and let me try the grinder, hours flew by. My family wondered what had happened to me (all they knew was I was meant to be meeting a man off a coffee forum!)
My thoughts are with his friends and family, rest in peace.
