Thank you!
Ente was first a piece of hardware, then a self-host-able project, but we had a hard time monetizing both, which lead to the E2EE pivot.
TIL about TagSpaces, thanks!
Our server can be open-sourced, but we're unsure of the value E2EE will provide, with services like Photoprism[1] and Immich[2] already doing a good job of serving customers who prefer to self host. In this context E2EE might become a constraint, rather than a feature.
