A pure analog recording can be superior to digital recordings. But those are so rare these days, we don't have a good comparison.
There's things like "bass bleed" and cross talk that made analog so interesting to listen to.
As long as the original recording is 48kHz or higher, digital recordings are awesome. We might not be able to hear beyond the 20Hz - 20kHz, you can most certainly feel it. Especially in the lower end.
My biggest question to FUTO/Immich is if they're worried about a revenue stream, why not do something similar to Home Assistant? You never have to pay HASS a dime and never see anything to "shame" you. All you get is essentially a forwarding subdomain with some "easier" ways of doing cloud related things. There's zero "shaming" or calls to pay. I pay HASS/Nabu Casa monthly cause I'm lazy and it makes my life easier. FUTO should consider doing something similar.
