I am reminded of Arthur Dent - had to go down into a basement, with a flashlight, and it was on display in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying ‘Beware of the Leopard.’
Not to argue the legal point at all, but if it isn't published or even notably advertised, its canon state is not particularly meaningful. Who cares if it is canon if most of the fanbase is unaware of it? Certainly, they cannot apply what they don't know in their games - leading to a 'canon" element that does not appear in the setting's actual use...
However, you could use the same argument for the WOTC Realms web pages or out of print realms material be they sourcebooks/novels/early Dragons and Dungeons/Polyhedrons/etc. I know for a fact that I'm missing many FR Polyhedrons and a handful or so of other sources. Does this make them less official canon because I, as a fan, don't have them? No it doesn't. Just because someone doesn't know of, or own, sources doesn't mean that those sources aren't official canon.
But I can name at least three or four sources that have Candlekeep mentioned in the web article or the dedication at the front of the novel/sourcebook because there has been three recent novels with a dedication to Candlekeep.com as well as Realms web pages on WOTC's site that mention Candlekeep and give links to the site. Brian's sourcebook, the Grand History of the Realms, was mostly worked on at Candlekeep and WOTC's interest in it was because of Candlekeep. Ed, at Gencons, repeatedly says to go to Candlekeep if you want to discuss the Realms with the authors/game designers. I was there last year, so I know this.
So, Candlekeep is known but only if you read web pages, novels, and or listen to authors/game designers at Gencon. Or even read, if you know the web addresses, the online journals of FR authors/game designers. Plus many of us on Keep have, or still are, on the WOTC FR message boards and Candlekeep has been mentioned, repeatedly, over there for the past three or four years. Even here on Enworld we've had our fan FR compendium posted as news on the front page.
For example here's two:
Erik Scott De Brie, in his Depths of Madness dedication, "The scribes at Candlekeep: Sweet water and light laughter."
Ed Greenwood and Elaine Cunningham in their Waterdeep novel, "To all the sages and scribes of Candlekeep, and to The Hooded One for gracing the loreseekers of cyberspace with her tireless efforts and effortless charm."
So all I'm saying is that yes, some people might not know that Ed's words are canon but at the same time if someone is seeking an answer about homosexuality in the setting, I, for one, wouldn't discount the words of the settings creator since the companies that published the setting either had a Code of Ethics which made the topic hands off or the company chooses to not discuss it because it'll anger some fans/parents/etc.
