I feel you’re coming at this from an abstract angle more than how these things actually play out in practice. This isn’t reliable software, it isn’t proven to work, and the social and economic realities of the students and families and districts have to be taken into account. The article does a better job explaining that. There are documented harms here. You, an adult, might have a good understanding of how to use a monitored device in a way that keeps you safe from some of the potential harms, but this software is predatory and markets itself deceptively. It’s very different than what I think you are describing.
