Paranoia is justified if it actually serves some purpose. Staying paralyzed and not doing anything because Someone Is Reading Your Data is not serving much of anything. Hint: those Someones have better things to do. LLM vendors really don't care about your bank statements, and if they were ever in a position to look, they'd prefer not to have them, as it just creates legal and reputational risks for them.
You don't remember when people were generating private keys and tokens using github copilot in the early versions? I'm not sure if they ever completely fixed the issue, but it was a bit scary.
