The main thing that turns this problematic, is the reason behind the event.
if it was just to celebrate the american exclusive event, that's cool.
but since they are doing this because of the increase of asian hate, something that isn't an exclusively american problem, it makes it look like they only care abou the American asian hate. aka, if asian hate happens outside of america, it doesn't concern them.
This surely isn't their intention!!
it's just what this approach implies when they are holding the event not to celebrate the american-asian culture (which is unarguably a unique experience to, idk, brazil, or italy, or south africa. seperating that would totally be fair) but, as they have stated, to do something in light of the asian hate.
because it says "we care about Asian hate, but only when it concerns asian-americans"
in the end they are a bussiness, so even charity or awareness campaigns, do boil down to business desicions and shouldn't be taken too much as a symbol of how much the company cares about its audience and users.
