In the Orion FAQ the question "Is Orion open-source?" is answered enthusiastically with "We're working on it!". (https://help.kagi.com/orion/faq/faq.html#oss)
I think I misinterpreted this to mean that the team is actively working on this and we can expect this soon. However, from the discussion here and on Discord I understand that for various (legitimate and understandable!) reasons this is currently not a priority. Should the FAQ be updated?
(I don't know if enough users feel this way, but if Kagi were to provide a concrete timeline for going OSS, I would definitely add Orion+ to my Kagi subscription.)
