This. It's the same innocence of people who believe when you delete a document on Google/META/Apple/Microsoft servers, it "really" gets deleted. Google most likely has a backup of every piece of information indexed by them in the last 20 years or so. It would cause envy to the Internet Archive.
- Google: active storage for "around 2 months from the time of deletion" and in backups "for up to 6 months": https://policies.google.com/technologies/retention?hl=en-US
- Meta: 90 days: https://www.meta.com/help/quest/609965707113909/
- Apple/iCloud: 30 days: https://support.apple.com/guide/icloud/delete-files-mm3b7fcd...
- Microsoft: 30-180 days: https://learn.microsoft.com/en-us/compliance/assurance/assur...
So if it ends up that they are storing data longer there can be consequences (GDPR, CCPA, FTC).
