What difference does that make in solving the actual problem? The real story here is not "some lousy Microsoft employee ripped off this guy's graphic", but "people using AI image generators may receive near-copies of existing media instead of new content, with no indication that this has happened".

If this has been discovered once, it must be happening every day. What can we do about that? Perhaps image generators need to build in something like a Tineye search to validate the novelty of their output before returning it.
