That guy was talking about grayjay, a Client to follow creators on multiple platforms at the same time. Grayjay isn’t licensed under AGPL, but instead it uses the FUTO Temporary License. It technically still counts as source available, but I think the NC-Part is okay to have. AGPL would be nicer though especially bc of this.
I could understand the argument if Immich relicensed to the FUTO Temporary License, which technically isn’t open source, but since immich is still AGPL this makes absolutely no sense
