Not really, this is a whole load of made up outrage by the anti woke police who seem to think there’s some kind of agenda behind everything.
The names for these products is focused grouped to hell and back. The product is aimed at kids who may never have even seen EP4-6. The ships name is not mentioned outside of a few obscure comic strips and only adult fans are actually going to know the name.
If you actually look at all of the Lego star ships released the Slave 1 is one of the few ships referred to by its ‘Nick name’, the mother notable one is the Millennium Falcon which is said who knows how many times in the films.
If I asked my wife which characters ship was slave 1, she wouldn’t have a clue but she’s seen all the relevant material. That’s the point of the change.
If a kid asks their parents for ‘Boba’s space ship’ how are they going to know that is Slave 1?
Most ships are either called ‘X characters ship’ or the mode name (X-wing) if it’s mentioned in the films or a generic name that describes it (imperial shuttle).
If anything this ‘change’ just brings it online with most other releases and is way more relevant to those who may want it (kids) and wouldn’t actually know what it’s called because it’s a piece of obscure trivia.
Not only that the name is pretty rubbish, Boba Fett’s role has massively changed since EP5/6 (was a villain, now a hero) and it doesn’t really relate to that at all.
Like I said, it’s fake outrage nonsense that shouldn’t really matter but for some reason some Star Wars fans seem to think Disney has this agenda that is against them and this just fits their narrative so they can have a pop on the internet.
The reality is:
Focus groups
Marketing
Making it easy for parents to buy the right thing
Profit
Aka how business make more money. Alternatively they may just not want slavery being linked to the product, but either way it doesn’t really matter because changing the name for this product actually makes sense because of who it is aimed at.
