> The premise here is that search is an integral part of the product experience of using Google Workspace. We don't offer controls that separate each piece of functionality within Workspace products. The reason there _is_ one governing both Workspace and non-Workspace data (the current Web and App Activity setting) is mostly historical in nature, and the fact that there are two existing controls (one for the admin, one for the user) means the vast majority of users don't even have the chance to try the feature out to figure out if it's useful for them.
That's a very elaborate way to say "because we don't want to".
I disagree. I think the point is reasonable. I personally find it useful to refer to my past searches/activity, especially in a professional context, and it would be unintuitive to me if such a feature was turned off by default.
