This was the push I needed to switch to Graphene. The Gemini offer popped up for me a couple of weeks ago. The only options were something like 'Yes' or 'Not now'. No option to say never, which of course means they would bug me again and again.
Thank goodness I switched to Apple before this nonsense got deployed; their Apple Intelligence is opt-in and not being forced on users. Google and Microsoft truly botched the deployment of their LLM experiments by forcing it into first party apps and not giving users a choice.
