> * GDPR/Privacy laws (The law requires the deletion of no-longer needed data. As soon as his account gets banned, the data is no longer needed for Googles business purposes (of providing service to him), so the deletion process can't be delayed.

I do not think GDPR works like that. You can absolutely store information pertaining to "why" questions because that is still a service they will be providing. Also, whenever they restore some's service they give data back. So they have obviously not deleted the data.
