Found this absolute gem in the process though:

"Nostr’s origins are mysterious. The name does not appear in the U.S. trademark database. According to WhoIs, the Nostr.com domain was originally registered in 2003 (almost certainly for some other entity) and brought back to life on November 29, 2022, by a person or persons whose names are shrouded. The service’s founder is known only by a pseudonym, “fiatjaf.”"
