They are complaining because a spaceship named Slave-1 (which is extremely famous and important as we all know) has been renamed for a LEGO kit as "Boba Fett spaceship".
Which is obviously SJW censorship and not simply a maerketing play because the name Boba Fett is more famous than "random ship-number".
I think that's the only reason I know what it's called. I somehow never saw that edit with the acapella version and I've been a fan since like 2007
