Instantaneous deletes might be impossible, but I really doubt that it’s physically impossible to eventually delete user data. If you soft delete first to hide user data, and then maybe it takes hours, weeks, months to eventually purge from all systems, that’s fine. Regulators aren’t expecting you to edit old backups, only that they eventually get cleared in reasonable time.

Seems that companies are capable of moving mountains when the task is tracking the user and bypassing privacy protections. But when the task is deleting the users data it’s “literally impossible”
