The antisemitism thing doesn't even make any sense.
From what I understand it's already established that evil queen Joanne wasn't involved in making the game. The game's only connection to JK is via the IP itself, and that connection is the basis of the attempted boycott. There's no wrongthink in the game itself.
So by what series of events do they believe the game became deliberately antisemitic?
A) This is just something they do in big budget games, and it's totally coincidental that it's in a product they're looking for any excuse to skewer.
B) The writers/developers, I guess due to exposure to a bigot's aura, became corrupted to the point that they had to start inserting antisemitic dog whistles into the game purely for personal satisfaction.
C) JK is able to skillfully sew hatred into the fabric of everything she does, such that anyone who tries to adapt her work will wind up making something bigoted; you're busy typing away writing some content for a Harry Potter property and you proofread your work only to realize oh jeez! This is actually a detailed plan on how to build mobile gas chambers.
D) This was some kind of stipulation passed from JK to the publisher: it's integral to the spirit of Harry Potter that you make sure the goblins are a fairly obvious Jewish analogue, and that you make veiled references to Jewish genocide; Warner Bros Games maybe thought that was a little weird but trusted her artistic vision.
Meanwhile the most compelling reason to not buy the game remains because being a corporate consoomer obsessed with series for children is no way to go through life, and also that nobody should be paying $60 for videogames.
Comment from a Jewish user on Kotaku.
The Jew is right, goblins may themselves have been based in part off antisemitic caricatures, but at this point it's an established fantasy trope.
It's kind of like when the same crowd went after Cyberpunk 2077 for not providing explicit pre-game epilepsy warnings even though that's not actually something any game does. No thought whatsoever, just feed them a line so they have something to parrot while they chimp out.
