They are specifically claiming that they were unaware and it happened due to the artist using the built-in AI aids in Photoshop, which is against their policy.

I actually trust WotC on this depite despising basically every other decision over the past year that they have made. They have repeatedly made their stance on not wanting AI content clear but individual designers and artists are easily equipped to just ignore that and only get caught when they don't clean up the obvious AI errors afterwards. WotC need to be fair better at internally vetting their art and I recon they are with card art or art that is making its way to books, but art from marketing and other adjacent areas is slipping through the cracks.

Initially denying the art being AI generated is actually probably the biggest tell that they didn't intend it. If they make a policy against it and get obviously caught, it's totally illogical to deny it and damage their reputation further, but if they trust the artist initially, then they have grounds to deny it until they vet it or the artist owns up, which is probably what happened here.

Hasbro on the other hand only care about one thing, the line going up to their investors can cum. Currently the only reason that WotC has such a strong anti AI content policy is because the heart of their content is about design, from their artists to game designer, and many of the people who hold these roles are beloved voices in the community and if their jobs are at risk, they'll be loud and clear about it, and we need to hear them and support them when Hasbro try to encoach on this policy, and make it clear that any cost-cutting from AI generated content will cause enough outcry and boycotting that their stock price goes down.
