Yes, definitely a positive. Although I would like it to go one step further and maybe talk about those creators and what they've worked on. Simply listing out names doesn't really add much imo.
But getting marvel and DC to hire more poc creators? I'm pretty sure they are aware of poc comics creators. They just mostly don't hire them. I would also say swearing off marvel and being public as to why can help the cause for greater diversity in comics. Marvel can understand that they are leaving some money on the table by not actively addressing their lack of poc creators.
Yeah, it has a lot to go for sure, very small credit is all - cuz of course the overall logic is stupid. But I understand why they would tend, as a business, to do retreads of what amount to a clique of white dudes. Business-think is to replicate successes - even if they don't entirely understand what made them successes. As for the swearing off of marvel, they'll still have a dedicated marvel section on that site and it makes it ring hollow to me. They'll still give them free coverage & attention - again, business-think taking the wheel. Thats where the ball falls into "our" court, I feel. They know they're leaving money on the table to some extent, but pointing out exactly how to recollect that money is better, to me. We say it all the time here to honest newbloods; follow writers/artists instead of characters. Being only a couple years into this hobby, I feel like I don't know a ton of creators, much less minority ones - but I would like to, and I'm not getting any help from people swearing off in favor of nothing. Like, I lack the awareness, and I think it falls to comics news sites and/or communities to help.
I guess my stance is pointing at a thing and saying "that's bad" is less useful to me than pointing at a thing and saying it's good. I guess it's what makes this community extremely good, to me.
heck, that's a lot of words. sorry.
