Which they did. They even included the URL of where it was inspired from.

And even so, it's not up to you to determine what follows the license and what doesn't. It's up to the author and his lawyer(s). Microsoft may have already asked for permission to do what they did, none of us know that.

Not linking the original location is a fair point and I've fixed that. --Immo

Art is about stealing and remixing, whilst noting where you got things from. I'm sure Randall understands this, and would not object.
