You and StarWarsTheory both seem to forget that Legends are not established lore, and honestly, it never was. Disney didn't decanonize it, simply because it was never canon in the first place. You know what George Lucas himself said about it?
“There are two worlds here; There’s my world, which is the movies, and there’s this other world that has been created, which I say is the parallel universe—the licensing world of the books, games and comic books.” - George Lucas, Cinescape, July 2001
“I don’t read that stuff. I haven’t read any of the novels. I don’t know anything about that world. That’s a different world than my world. But I do try to keep it consistent. The way I do it now is they have a Star Wars Encyclopedia. So if I come up with a name or something else, I look it up and see if it has already been used. When I said [other people] could make their own Star Wars stories, we decided that, like Star Trek, we would have two universes: My universe and then this other one. They try to make their universe as consistent with mine as possible, but obviously they get enthusiastic and want to go off in other directions.” - George Lucas, Starlog, August 2005
But instead, the fandom menace gets obsessed with children stories to such a degree that they start nitpicking on things like a random side characters alleged birth date or screws and bricks being used in manufacturing of Death Star parts, lol.
