While Gaggle is indeed crazy intrusive, they're not really alone in this world of K12 monitoring. GoGuardian and Lightspeed Systems are doing the same thing, perhaps to a lesser degree, but maybe not.
For example, administrators using GoGuardian can get 'Smart Alerts' for 'self-harm' and other objectionable material. They'll receive an email that includes a screenshot of the material in question, and for G Suite, it spans Google search, Docs, and effectively any Google service.
However, that said, I just tried to pull up a link for GoGuardian and noticed they have this disclaimer:
"Please note: Smart Alerts for the "Self-Harm" category is no longer available for new customers. For more information, please reach out to your sales representative."
