Why do you doubt that is exactly what is happening? The EU governments are demanding to view all communications by it's citizens AND has given itself the right to use all sorts of AI technology (like facial recognition) on private data (like faces for example). Privacy protection, even for your medical records, only exists against private companies. Which means that the people you want privacy from, your medical insurance, which is part of the government nearly everywhere in Europe, both has access and can do with the data whatever it wants under EU legislation.
Does anyone seriously expect EU legislation will protect people from the obvious: training AI on chat messages and then using violence (ie. police action) just based on online messages?
