I would be surprised if they did this for Workspace accounts. Deleting data from a organization would be a disaster for Google. I.e. an account may be at a center of a lawsuit or subject to data retention laws.
Hmmm is my G Suite account different from a Workspace account? I got this email a few weeks ago saying I hadn't logged in for awhile and they were going to delete my data: https://i.imgur.com/XAEXQWb.png
This subthread is confused. Google will delete long idle nin-domain users and idle domains, but will not delete long idle users within an active domain.
This I believe only applies to the root/admin account of the GSuite domain. Extra users created in the account are just extra user slots for that account.
Indeed, this says no:
