There is literally a thread somewhere on my Lemmy I need to try and find just recently that shows this perfectly. Someone made a thread asking how they can self host their images for backup from their phone and naturally everyone pointed them to immich. And they immediately started complaining and bitching that they could not access it from outside their local network. Instead of asking how to fix that they were like what the hell is the point if I have to be on the same Wi-Fi this is stupid. And they basically did not want to engage with the people being like hey you need to either make a reverse proxy or open a port on your router. They should not be self hosting
