That doesn’t have anything to do with the announcement. What the announcement is saying is: previously, if you wanted Gemini to have access to text and chat apps, you also needed to enable Gemini Apps Activity, i.e. the feature that saves all Gemini interactions to the cloud. Now, the settings to enable or disable app access from history tracking are fully separate, so you can have app access enabled (if you want) even if the Apps Activity feature is disabled.
