The wording used was 'a wok is unwieldy and uncommon in a lot of home kitchens'.
As one of the two Asian writers who this got past, we believed that this statement was true enough for North American beginners looking to learn how to make scrambled eggs.
I have changed the copy there and endeavour to make sure that we are more culturally sensitive in the future.
So your target users are North Americans? That's a pity. When reading your linked websites I got hope that Europeans were also included, because you are saying 'A giant opportunity in making cooking easier for a billion people' and 'Because a billion home cooks is good for people and great for the planet'.
You did nothing wrong. As a European I didn’t even have a clue what a wok might be for most of my life. Buying one would make no sense.
They didn't "teach" a "lesson" on racism, they said an entire 15 words in an edit and gave a range of "sheltered" to "at worst, practically racist". A bit hyperbolic? Sure. A lesson? No.
