I think some of the division comes from people more familiar with old EU Boba or how he was generally characterised pre-AOTC vs. people more familiar with the ‘softer’, more sympathetic Boba of TCW and similar. Finally escaping his father’s bounty hunter life and putting down some roots is kind of a warm/happy direction to take his story, but it’s very much a continuation of AOTC/TCW sad Boba’s arc, and not so much the heartless guy his original ESB voice and ‘no disintegrations’ etc. implied.

Turning villains into antiheros is always a bit controversial because it feels like a cop out, but this is Star Wars after all, which has always been very soppy about that sort of thing - people blame the ‘family-friendliness’ on Disney, but Lucas was just as insistent that Star Wars was for children and should generally be positive (it’s even rumoured that the Underworld series that was written but never produced under GL would have had the Emperor gain a sympathetic, tragic backstory of some kind).
