alt Hacker NewsDevils advocate here. There is currently an article on the front page about a US bill to compel operating systems to collect age verification / id data. If something like that was actually in place and every packet on the internet was stamped with your digital id then you could feasibly demand that aws purge/filter your data out of their systems.
You can't even request AWS delete your actual PII from S3. If you've been to a doctor in the last 2 years, you have HIPAA PII somewhere on S3, and AWS won't do a thing about it for you. I don't know why people have this idea that service providers will scrub their customers data for you.
