Randall definitely has significant artistic talent, but there are hundreds of examples from xkcd that absolutely support the argument.

Jesus Christ, you just made a compelling argument on behalf of rage comics. I’m pleasantly impressed.

On top of everything others have said, there’s no watermark, signature, url, etc from an original artist. Webcomics like this will always have one unless it’s removed by a reposter, which yeah, that happens, but I feel not as often these days. And when it does, it’s a pretty shitty thing to do, and not a good situation either.
