Personal head canon is that Ezra would be seen as this super chill, super awesome, super handsome Jedi Knight by the New Republic citizenry EXCEPT for his deranged attachment to using ‘Jabba’ as an alias.
You search his name on the Holo-Net and Jabba’s pic comes up. That’s how often he uses it. (Ezra is delighted by this; Sabine decidedly less so.)
