If framework did as you suggest, they would have no way to validate warranty status and recalls.

Motherboard died after 3 months? Tough luck, they have no record of you being a customer.

Battery tends to catch fire? I guess they should just post a recall notice to Twitter and hope most people see it somehow.

These are bad examples.

Warranty status is tied to hardware* serials. It's not like there are third-party Framework sellers.

Sending a recall notice via email doesn't require name, address, dob, etc.

Companies are in a bad habit of not actually clearing customer data they don't need.

Of course they do. How do you think warranty works for in-person cash purchases?

Put a sticker with a unique ID on parts.
