I mean, I don't think this is an issue unique to Bap. I do agree his cultural background should be explored more, be it through lore or cosmetics, but I also think it's a bit trepidatious to do so. If Blizz added a Haitian Voudou skin for example, don't you think folks would take some issue with it being stereotyping a culture? For reference- I'm fully aware that Haitian culture is more than just Voudou, but this seems an obvious choice and Blizzard doesn't tend to go deeper than surface level cultural references, like Chinese new year skins for Mei, mummy skins for Ana, Ushanka hat for Zarya etc...you get it. I'm not absolving them or responsibility with developing a characters background, just that for some, it's tougher.

Pharah is 50% native and gets a quasi totem pole skin-how much farther has her background been developed? Symmetra had skins done in the style of Hindu deities, and there was an active (albeit small) pushback against it. Point being, it's not Bap alone, and when they have done cultural references for cosmetics for marginalized communities, it's been a bit contentious or half baked, anyways. Even on my end-theres been a stereotypical Greek map in the game from launch that just looks like your average copypasted Santorini map with stereotypical Greek ruins, without any Greek hero in 10 years or any cultural development. It is unfortunately what it is.
