Per statements by companies:
"Our customers expect a human touch to our releases, and so long as the ethical and legal circumstances surrounding these programs remains murky and undefined, we are unwilling to associate our brands with the technology in any way."
or:
"Our internal guidelines remain the same with regard to artificial intelligence tools: We require artists, writers, and creatives contributing to the Magic TCG to refrain from using AI generative tools to create final Magic products. We work with some of the most talented artists and creatives in the world, and we believe those people are what makes Magic great."
and, after being confronted by customers for using generative features in marketing images:
"Now we’re evaluating how we work with vendors on creative beyond our products – like these marketing images – to make sure that we are living up to those values.”
and in marketplace advisement, such as:
"AI art, AI writing, or algorithm-based creation is prohibited on the Infinite Platform. Any product posted to Infinite that contains AI-generated art or writing where very little human work was done is subject to removal."
In practice, this has included artworks that were primarily human-generated but used tools like generative fills, and texts where creators admitted that they used generative AI to supplement, edit, or restructure their own writing.
In chat rooms and on social media where creators in this field congregate, they raise products to each other that they suspect contain generative AI, investigate them together, and collectively report them to marketplaces until the products are removed.
