I'm happy for them. Immich, along with Nextcloud, was the driving force behind my getting in to self hosting - getting away from the ridiculous and increasing subscription prices associated with keeping family photos and documents.
It has come an incredibly long way in the time I've been using it. I've kicked them a donation or two, a first for me with OSS, because it continued to provide so much value for me.
I had read earlier that Alex was hoping to transition to working on this full time and I am happy he has been able to see that realized in - what appears to be - a positive manner.
