There are stories after stories of students getting shafted by gullible teachers who took one of those AI detectors at face value and decided their students were cheating based solely on their output.
And somehow those teachers are not getting the message that they're relying on snake oil to harm their students. They certainly won't see this post, and there just isn't enough mainstream pushback explaining that AI detectors are entirely inappropriate tools to decide whether to punish a student.
That sounds like an improbable attempt to leverage the notion that minors can't enter into a legally binding contract into a loophole to get anything for free by simply having your kid order it.
