FUTO could technically scrap the current version, grab the last MIT version of the code, relicense it under their "source-first" license (or any other license they like, pretty much), and declare "this is now the official development version of Immich from which new releases will come."

If they pulled that off, a community spinoff from that same version would become the new immich killer. Not the first time it's happened, and the current maintainers aren't the only ones capable of maintaining it.
