Google buried the Gemini off-switch. That is itself a product decision.

There is no 'turn off Gemini in Docs' button inside Google Docs. To disable it, you navigate to Gmail settings, find smart features, toggle off two separate options in a submenu called 'Manage Workspace smart feature settings', and accept that you will also lose spell check and smart compose in the process. Consumer Reports, CNET, and Digital Rights Watch are all now publishing step-by-step guides on how to escape Gemini, Apple Intelligence, and Copilot, which is a reliable indicator that mainstream user friction has crossed a threshold. The business risk for Google is churn among enterprise and professional users who handle confidential documents and are genuinely uncertain whether Workspace content is training Gemini models. Google's design choice, default-on AI with an obscure cross-product opt-out, maximises adoption numbers while creating a trust gap that competitors with cleaner consent flows can exploit.
