if they make it almost exactly the same and “credit” it in the smallest font possible and didn’t get permission from the original author… i would say that’s definitely a ripoff
Tell me you don't know xkcd without saying you don't know xkcd. These comics are licensed as CC-BY-NC 2.5, which means you are allowed to remix and use them, without explicitly asking for permission, as long as you attribute the original/author (which is given here) and as long as you do it non-commercially (which is given for this post IMHO).
quoth wikipedia: "A parody is a creative work designed to imitate, comment on, and/or mock its subject by means of satirical or ironic imitation." ... "The literary theorist Linda Hutcheon said 'parody ... is imitation, not always at the expense of the parodied text.'"
In a version that doesn’t even fully make sense. With databases there is a well-defined way to sanitize your inputs so arbitrary commands can’t be run like in the xkcd comic. But with AI it’s not even clear how to avoid all of these kinds of problems, so the chiding at the end doesn’t really make sense. If anything the person should be saying “I hope you learned not to use AI for this”.
