We’re going down a lot of rabbit holes here. That was an assumption based on the hypothetical idea that they both used the same copyright free image. Or maybe Disney bought the image. Or maybe the Disney designer also owned the Redbubble store. Etc, etc, etc.
My fault for getting too far into hypothetical land. Back to my original point. None of us know what happened. It seemed to me that there was a quick rush to judgment when, again, no one knows what actually happened. There are some situations that I think would be pretty innocuous, and some that would be concerning.
