The *original* Voodoo Boys were a cultural commentary on appropriation, per Pondsmith himself - hence why they were overwhelmingly white. CDPR's version of the VDBs as Ayisyens(Haitians) was supposed to be a nuanced portrayal commenting on how the community was oppressed in NC, according to their interviews. Hence why the VDB moniker in their iteration was not a name they took on for themselves, but was given to them by outsiders. They're supposedly not practitioners, despite their interpretation being that the community was founded by a "caste" -lol - of houngans and manbos (the names given to priests and priestesses) from the religion, which is a weird premise in itself since it's a communal religion. In addition to this, a bunch of graffiti undeniably implied to be vèvès (vay-vays) litters their neighborhood, which are actually sacred religious symbols representing different Lwa rather than the randomly-designed scribbles their art team used. Even a symbol found during the BD leading to the Pacifica arc is supposed to be a vèvè, but it's just a heavily stylized and altered vèvè of one of the Brijits with a skull added to it and it's used again during a funeral meant to be taken seriously. There is even a Cyberpsycho killing people to get to "the Promised Land" because of some unnamed Lwa appearing to them during an episode, even though that is literally not how the religion works at all.
I don't expect them to get the intricacies perfect, but if you're going to include a culture as well as religion that has been shunned and discriminated against for centuries, you need to come correctly. Given how awesome them being Netrunners concerned for their community foremost is, it's a heavily-missed opportunity only worsened by the player not having any true chance to immerse themselves in their interpretation of the lore.
