tldr is that you can hide the button that asks for payment and it says “purchase immich” instead of “purchase liscence”
They do, but I don’t think that would apply to Immich. Immich is under the AGPL, and hasn’t taken on any FUTO licensing. In a QA they did awhile back they said there was no plans to change it as well, so should be AGPL for the long term.
As far as I’ve seen, the only connection that Immich has with FUTO is the $1M grant and continued development support. I would imagine any sales from these Immich server purchases are now obligated to go to FUTO, but that’s the only connection between the two companies.
