Is there a chance that Amazon spoiled Finn’s family name? I don’t think so. It seems like an assumption by the poster of that item. The poster is an individual seller on Amazon and NOT Amazon itself. If Lando is of African descent and Finn is of African descent then they MUST be related. Short of tossing around the word “racist”, I’ll just call this one plain ignorant. [sigh]
Another piece of evidence pointing at the poster’s ignorance is that they use the word RARE.
Look, this person could be correct. I’ll give that to them, but the chances of that are very low. Would it be cool if Finn was the son, or grandson, of Lando? Sure! Personally I would rather that Billy Dee Williams, himself, appear in the film. It’s more likely that this is either wishful thinking, ignorant marketing, or somebody out to troll the internet. If it is the later then they have succeeded.
Keep it simple my friends. Don’t over react and the Force will be with you ^_^
