Most open-source programs recommended as alternatives don't offer any customer support either. For non tech people the chance that they mess something up is pretty high, which a lot of people seem to forget. For them something like iCloud would be a way better alternative than "Immich".
iCloud is great. I ended up switching to iCloud. I could contact a person when there is an issue, and there are some common senses in Apple to solve problems, solutions are more well thought from customer's point of view. Google reminds me the time when all softwares display error code on screen, and menus were designed by programmers.
