Oh come on, Proton, you're supposed to be better than this. Chatbots are proven privacy-violation engines. If you're going to act like Google, there's zero reason to pay for your services.
It's opt-in, open source, runs on device, does not use your emails to train the model, and most important of all does not grant Proton access to your emails.
What part of that do you see as a privacy violation?
