If this article’s accurate, Disney Ulic has the same exact history as Legends Ulic. Tom Veitch originally intended Ulic to die unredeemed. Why couldn’t the new writers honour Veitch’s vision and provide longtime readers a fresh, new take on an old character? There’s a painful dearth of creativity at play.
Wookieepedia counts an RPG that began before the end of Legends and Italian magazines as “canon”, so I think they’re too quick to declare things canon and I wouldn’t go by them. In fact, the “canon” Ulic Qel-Droma article you linked to lists the RPG I mentioned as its only source.
