The alliance is HW manufacturers alliance, there’s samsung and lg there, as pointed above those are not really supported by lineage or /e/ etc, it seems unrelated, jolla is not part of the alliance, they offer flashable images, like lineage or graphene, noone cares about 2005-6 thing, with wikipedia article not even being updated past 2011, it’s long past gone, you can unlock bootloader on pixels just fine, so really not seeing your argument
