I made it one day on a whim while working on really early versions of the Ghost ship, and it's remained unchanged all the way through marketing.

'I'm probably most proud of the Rebels' phoenix logo. The Rebels version of the Starbird logo was designed by concept artist Chris Glen. (The Legends canon explanation is based on the Marek Family Crest, but the Marek Family is no longer part of canon.) We can therefore speculate that the final Rebel design may be a combination of these two - evoking both the rebirth and rebellious spirit of Sabine's Starbird, and the history and hope of the Jedi Order. The visually-similar Jedi Crest obviously predates Sabine's logo, and was worn by Jedi generals on the shoulders of their armor during the Clone Wars. However, by Season 2 the show hasn't reached the point in history where the familiar crest comes into general Rebel use, but the design of Sabine's Starbird is clearly intended as an origin of the cleaner crest we know so well. Sabine later joins the similarly-named Phoenix cell lead by Commander Jun Sato, part of the fledgeling Rebel Alliance lead by Bail Organa and In Star Wars: Rebels, Mandalorian weapons expert and painter Sabine Wren uses a stylized Starbird (based on a mythological bird similar to the Phoenix, which can never die and renews itself in a nova) to tag Imperial ships and propaganda on Lothal.

But it's likely based on Sabine Wren's personal Starbird graffiti tag and/or the Jedi Crest. In Disney Canon its origin is currently unconfirmed.
