I find this an odd take. Xbox is overall the platform with the smallest userbase on VGC to my knowledge, afaik it's Nintendo > Sony > PC > Xbox. As far as I'm aware the preferred platform make-up of the mod-team is largely proportional to the overall userbase on VGC as well, and same for the writing team.
Nintendo for sure is #1 but I'd say Xbox/Sony are above PC userbase...But then I think about the PC users who don't really talk about it.
As for the Mod team, I'm fairly sure only myself and Machia would call ourselves predominately Xbox fans, Lol. I'm a secret Nintendo fanboy though. Our boss is primarily a PC/Sony fan and his boss (Machina) I don't even know, PC? He never talks about it, Lol. I don't tend to go around asking all the Mod team members their primary preferences...
But I think it's safe to say that there are more Sony fans on the Mod team than Xbox fans and about an even split between Xbox-PC-Nintendo for the rest. I'd say the majority of the Writing team are Nintendo fans but only Trunks does the news writing, the rest do either reviews or opinion pieces, something that Trunks never does.
