It's an interesting issue. I agree that any cultural, sacred image, should be treated with respect. Regardless of a person's personal beliefs (but that's a whole other topic).
But it's sort of a double edged sword of the global village, isn't it? Someone sees something that they identify with and they want to emabrace it and make it part of who they are, so they adapt and modify it into something uniquely theirs but inspired by X. That's actually a pretty pure motivation in some ways.
Then there are companies that use these images in their designs with no religious significance at all but simply for the visual appeal. The consumer sees it, something clicks and they buy. Maybe it never goes farther than that. But maybe they think, "Wow, this is really cool" and choose to learn more about where that image came from. All of a sudden you have a person in the USA who becomes inspired by and aware of a different culture. Probably also a good thing.
But in the process the imagery has been watered down. It's no longer meaningful. And a culture may become offended.
It reminds me of a chinese proverb, "Good luck, bad luck, who knows"
I certainly don't have the answer.
But I am pretty certain that it can't be stopped. In the current world of instant sharing of images and ideas, it's inevitable that people will run with ideas and inspirations driven by many different undercurrents of intention and I don't think it can be controlled.
Living life like there's no tomorrow.
