Not everyone has the technical ability or hardware to selfhost immich, even just for LAN access. If I tried to teach my wife enough about docker/docker-compose to get immich set up, running, kept updated, and troubleshooting when it has problems... I would probably be limping away with a fork stuck in my leg. Could it be a fun project for people that are interested in it? Definitely, but most people want an easy cloud service that works as easily as data-gathering alternatives over something they have to maintain themselves even in the form of occasional docker-compose pull
