Should questions about the history of the open source idea or open source projects be on topic? The closest I've seen to one is How could using code released under CC0 infringe on the author's patents?1, originally titled "Why wasn't CC0 approved as an open source software license?", which seemed like a good one. A historical answer isn't necessarily necessary for it, but an answer would have to take into account the arguments regarding potential approval/rejection/withdrawal.
1 The title has been modified, which may have given it a different tone.
