I don't separate them. To still partake in the art helps boost their popularity and their message.
I also can't claim to support a group while boosting their biggest antagonist. I also see this spreading into the AI area.
If I see authors using AI cover art, I blacklist them. AI voices for characters in games? I'll swerve. I can't claim to support a community of artists and then shoot them in the foot at first opportunity.
It depends. Self publishers on places like Amazon Kindle are probably making that choice themselves. They choose their own covers.
I understand a Self publisher has less financial resources but.. there's no good answer.
For large publishing firms, they have a choice. They pick books they think will do well and support it with cover art, marketing, etc.
When you have things like Fallout's TV series using AI art to market itself? That's a multi-billion dollar company. They can afford not to. I don't fault the writer for a book that a publisher forces AI onto, but as long as they stay with a publisher who openly forces them to use AI, I will hold my stance.
What about collective works where only one person is problematic? The Cosby Show for example. It's watching The Cosby Show boosting its popularity and message? The message of that show is arguably a good one too, so that doesn't seem like a bad thing, and hundreds of other people made that show.
Cosby was the titular character. His actions reflect on everyone. The supporting cast and crew did good work and were paid (hopefully fairly) for it, and I hope their efforts will always be remembered but the work is also tainted now.
One thing I'm unsure of is if Cosby wrote any of the shows. If so, his creeping shadow gets worse because he's a hypocrite. If not, then it's unfortunate to the writers.
There will never be a black or white answer in this but I have to draw lines somewhere. I don't demonize the supporting cast, only the titular one.
The cast can and should denounce Cosby in cases like that but.. again, Apple and the bunch.
