Unauthorized Siri learning after Apple Account log-in

Siri setting on iPhone changes itself after log-out then log-in to Apple account.

Previously it was set to not allowed learning from any app.

After the recent log-in, Siri allowed itself to learn from a few apps, not all, just a selected few that can get it learning the type of things it want about my daily activity, like my language skill, my travel journey with a particular ride-share app, my usage of apple map, etc.

Had I not do a regular check I would not notice this intrusive changes.
