Great writeup. Glenn mentions that he stopped using Gemini. While I still use Gemini for technical research and occasional coding/design work via Antigravity, for all day to day queries and prompts I have switched to using Proton's Lumo that is really quite good: use of a strong Mistral model and web search is 100% private, and while chat history is preserved for a while it is stored and processed like Proton Mail.

More good reading that I found helpful are the books: Privacy is Power and Surveillance Capitalism.
